Recommended for: Boilers, wood stoves, solar water heating, refrigeration, SVO conversions, Heat Pumps, Central Air Conditioning, Industrial Water Cooling, Oil Coolers and any application where heat transfer between two fluids is required. Need help choosing a unit? Generally speaking, the longer the heat exchanger is, the more efficient it will be. Adding more plates reduces pressure loss and adds some extra heat transfer. More width on a unit also reduces pressure loss and adds some heat transfer. Since plate heat exchanger utilize convection, it is better to add length than plates or width for heat transfer when the flow rates are low. (adding more plates or width reduces fluid velocity and thus, less convection) For a specific sizing to your requirements, please see our heat exchanger sizing form.

DFD High Pressure Solenoid Valve DIN Wiring Terminal Electric Pneumatic Chemical

Heavy Duty DFD High Pressure Solenoid Valves Duda Energy Heavy Duty Solenoid Valves are made with thick valve bodies and extra copper containing coils for longer lasting life and higher stress taking applications. Need an Electronic Timer for Automated Control of your Solenoid Valve? Check out the Duda Energy Electronic Switch Timers Here. The DFD series valve is a two way solenoid valve which has 2 ports in which fluid flows from/to. These valves open/close with assistance of applied pressure from the working fluid. The valves require pressure to open/close because there is a high powered spring, which enables higher maximum operating pressures than zero pressure solenoid valves. Available in a body/seal material of brass/NBR or stainless steel/viton. Brass/NBR valves are suitable for water, hot water, gas, air, and non-corrosive oils. Stainless Steel/Viton valves are suitable for hot water, weak acids, weak alkali, chemical salt, oils and hydrocarbon. Flow of the Valve These valves only allow flow in one direction. Pressure from the working fluid is required to open/close the valve when activated. If flowing in the wrong direction, the valve may not be able to open/close. Electrical Connection The electric coil uses a DIM connector. This connect contains wiring terminals for easy connection and a simple connect/disconnect: Simply unscrew the DIM connector and unplug the valve for service (no need to disconnect the wires from the terminals). The coils are not polarized, which mean that positive/negative does not matter when wiring them. We highly recommend using the ground terminal in the DIM connector to avoid electric shock when touching the valve. Coil Use The coils are designed to withstand heat build-up from continuous use as long as they are exposed to ambient and not insulated in order to dissipate heat. Although they can be used continuously without shutoff, it will reduce the life of the coil to operate them constantly. DC valves will experience more rapid heating than AC valves due to the higher amperage required to operate them. Working Fluid The working fluid can be a variety of substances. The fluid must be clean of debris for proper operation of the solenoid valve. If any debris gets into the valve body, it can clog the diaphragm from a complete seal, thus preventing a a successful closure of the valve. In the event of clogging, these valves are easy to clean. Simply remove the 4 bolts holding the body together to access the diaphragm for cleaning. Model Numbers Model numbers are listed below for brass, normally closed valves. If stainless steel, a JV is to be added after the mm size. If normally open, a K is to be added after mm size and between the JV on stainless steel.

Available in: Port Sizes: 1/4″, 3/8″, 1/2″, 3/4″, 1″, 1-1/4″, 1-1/2″, 2″ Body Types/Diaphragm: Brass/NBR or Stainless Steel/Viton Voltages: 12v DC, 24v DC, 24v AC, 110v AC, 220v AC Need an Electronic Timer for Automated Control of your Solenoid Valve? Check out the Duda Energy Electronic Switch Timers Here. Free Shipping When the free shipping method is selected, most orders will ship by USPS Priority Mail. If multiple quantities are ordered for a total over $250, we may opt to send the shipment by Fedex Ground to ensure that the package is delivered with a signature so that there is no risk of a stolen package. Description A two way solenoid valve means that there are 2 ports in which fluid flows from/to. The Direct Acting valves will stop flow in either direction, but are still only designed to allow full flow in a single direction. Semi-Direct acting valves require assitance from fluid flow to open. These 2W valves open/close with a 0 psi working pressure. However, while they do not require pressure from the working fluid to remaing open or remain closed, the semi-direct lift valves do require some assistance from the fluid for the initial opening/closing. Some gravity flow applications may have trouble overcoming the static friction of the seals within the valve while initially opening or closing. General purpose 2-way direct acting and semi-direct lift acting valves. Common applications include water, oil (below 20cst), air, gas, freon, *vacuum, weak acids & weak alkali. Check chemical compatibility charts for the valve body and seals of the valves to see if they are compatible in the case of using a weak acid/base. *Only Solenoid valves of 1″ ports and smaller are able to operate with full vacuum. Available in a body/seal material of brass/NBR or stainless steel/viton. Brass/NBR valves are suitable for water, hot water, gas, air, non-corrosive oils and freon. Stainless Steel/Viton valves are suitable for hot water, weak acids, weak alkali, chemical salt, oils and hydrocarbons such as *Diesel Fuel. *Diesel fuel is compatible with Brass/NBR, however, it is known to slightly shrink NBR and with any small shrinkage of the material in the diaphragm, it can cause a solenoid vale to cease in operation. For this reason, we only warranty the stainless steel/viton valves for diesel fuel and similar applications. Flow of the Valve The Semi-Direct Lift valves will partially open or close from activation, and require fluid assitance to prop open or closed. They can only stop flow in one direction, which is indicated by the arrow on the body of the valve. If pressure is applied in the opposite direction, the valve will be opened and allow a slow trickle of fluid in the opposite direction. These valves should only be used for stopping flow in one direction. If preventing of backflow is required, a check valve should be placed in the line after the solenoid valve. Direct acting valves switch on their own with no fluid assitance and can block fluid flow in both directions. Electrical Connection The electric coil uses a DIN connector. This connect contains wiring terminals for easy connection and a simple connect/disconnect: Simply unscrew the DIN connector and unplug the valve for service (no need to disconnect the wires from the terminals). The coils are not polarized, which mean that positive/negative does not matter when wiring them. We highly recommend using the ground terminal in the DIN connector to avoid electric shock when touching the valve. Coil Use The coils are designed to withstand heat build-up from continuous use as long as they are exposed to ambient and not insulated in order to dissipate heat. Although they can be used continuously without shutoff, it will reduce the life of the coil to operate them constantly. DC valves will experience more rapid heating than AC valves due to the higher amperage required to operate them. The rated maximum power consumption often only occurs when the valve operates near the maximum pressure. When no pressure is applied, the valve’s power consumption is about 1/3 of the maximum power consumption. Limitations of the Larger Valves For the larger valves (1-1/4″ and up), when operating near the maximum pressure, it can take a little longer for them to close than the smaller valves. Because of this, some applications with larger valves may also experience a “fluttering” sound as the valve tries to close against the high pressure. Valves larger than 1″ cannot hold a full vacuum. It is recommended to use the smaller valves for vacuum applications, especially if near full vacuum needs to be achieved. Working Fluid The working fluid can be a variety of substances. The fluid must be clean of debris for proper operation of the solenoid valve. If any debris gets into the valve body, it can clog the diaphragm from a complete seal, thus preventing a a successful closure of the valve. In the event of clogging, these valves are easy to clean. Simply remove the 4 bolts holding the body together to access the diaphragm for cleaning. Model Numbers Model numbers are listed below for brass, normally closed valves.
