Media-separated two-port discrete pipeline valves allow on/off control of gases or fluids where the (metal) working components of the valves never come into contact with the process media. NITRA 2-position, normally-closed (spring return) diaphragm-type valves are available with 24VDC, 24VAC or 120VAC solenoids, and have DIN style wiring connectors.
The NITRA DVP-2B and DVP-3B Series valves are composite body solenoid valves offered in both 2-way and 3-way normally closed styles. Component features include a reliable solenoid operator available in brass/stainless or all stainless pilot design. The glass filled composite material is media compatible, eliminating the need for stocking multiple body materials. Features include:

The NITRA DVP-2C and DVP-3C Series valves can be stacked into a multiple output bank of solenoid valves. The DVP-2C and 3C valves feature a fully encapsulated coil, spring compensated plunger seats for long life, and a miniature stackable composite valve body.
The advantage to this design is the versatility to stock single units and build, mix, and match to meet specifications. In most cases these valves reduce inventory costs and lower installation costs over a conventional manifold valve series. The coils are supplied with DIN connectors installed. Features include:
DVP-2C and DVP-3C Series pneumatic solenoid valves are
The NITRA DVP-2D and DVP-3D Series valves are composite body solenoid valves offered in both 2-way and 3-way normally closed styles in three orifice sizes. A direct acting solenoid utilizing a long-life spring compensated poppet is at the heart of an all stainless solenoid operator.
Body construction is glass filled nylon with Viton seals, making the valves compatible with air, oil, inert gas, water and caustics (verify chemical compatibility). Other features include:

The NITRA DVD-2A Series valves are 2-way, 2-position, normally closed valves for the control of air, oil, water, or media that is compatible with valve materials. These valves feature an all brass body and a zero minimum pressure differential while still boasting a full flow 1/2" orifice.
Available in 1/4", 3/8" and 1/2" FNPT port sizes. The DVD-2A valves can handle pressures to 230psi. The encapsulated coil construction ensures that the valve functions well under long periods of energization (100% duty), as well as providing a high degree of environmental protection (NEMA Type 4). The inner valve functions as a direct assist using a flat diaphragm and orifice plate. Pressure differentials shift the valve to full open. A push, non-locking manual override is standard. Other features include:

The NITRA DVD-2B Series valves are engineered composite 2-way, 2-position solenoid/air operated valves designed for the control of liquid media and inert gas. The valves are available with a large 1/2" or 1-1/8" orifice and five port sizes, 1/4", 3/8", 1/2", 3/4", and 1" FNPT.
The compact design of the valve body uses the latest in material sciences with the use of composite materials. The solenoid pilot is power saving low wattage, made of stainless steel working components and is miniaturized to fit in tight places. The fully encapsulated coils are available in three voltages with a DIN connector attached. Typical applications are for installations where there is a need to control inert fluids and gases, condensate drainage, hot water plumbing and sprinkler systems. Other features include:
DVD-2B Series pneumatic solenoid valves are
The NITRA DVM-2B Series valves are media separated, dry operator, 2-way, 2-position solenoid operated valves for use with gases or fluids where the metal working components of the valves do not come into contact with the working fluid. Three orifice sizes are offered.
Body construction is glass filled nylon with Viton seals, making the valves compatible with air, gases, water and chemicals. Other features include:
