2/2 PILOT OPERATED PISTON VALVES

Product catalog summary

Technical Specifications:
The pilot-operated piston valves are available in sizes ranging from 1/2” to 2”. The valve body is made from brass or stainless steel, with internal parts also in stainless steel. Seals are made from PA or PTFE, allowing fluid temperatures from -10°C to +100°C for PTFE and up to +90°C for PA. The maximum ambient temperature is +55°C, and the valves can handle a viscosity of up to 21 mm²/s. The response time for opening is between 0.1 to 1 second, and for closing, it is 0.5 to 5 seconds. The valves operate on various voltages, including 230, 115, 48, 24 V AC, and 24, 12 V DC, with a continuous duty cycle (ED100%). They support a cycling rate of 10 to 100 cycles per minute and have an IP65 electrical protection rating when used with a plug conforming to ISO 4400. Long-term use in humid environments requires sealing sets.

Valve Operation:
The valves are normally closed (NC) when de-energized. They require a specific pressure difference for operation, detailed in the accompanying tables.

Material and Performance:
The valves are available with different port sizes and materials, including brass and INOX (stainless steel). The flow coefficient (Kv) and differential pressure range vary depending on the model and material. For example, a G1/4 port with a 6 mm orifice has a Kv of 10 l/min and operates between 0.5 to 20 bar pressure difference.

Options and Customization:
Explosion-proof coils (EEx me II), NPT ports, and other custom versions are available upon request.

Versions with INOX Body:
The document also details versions with an INOX body, which are open when de-energized (NO). These versions have different specifications for flow coefficient, pressure, and materials.
