Description

Normally Open High Pressure Stainless Steel Solenoid Valve – Up to 500 Bar

TheCNXHPI022CD15 is a specialist high-pressure stainless steel solenoid valve designed for demanding industrial, petrochemical, hydrogen, gas control and process applications operating at pressures up to 500 Bar.

Featuring a direct acting normally open design, the valve remains open when de-energised and closes when power is applied. This fail-safe configuration is ideal for critical applications where uninterrupted flow is required during power loss.

With stainless steel construction, PTFE seat technology and pressure ratings up to 500 Bar, the CNXHPI022CD15 provides reliable operation with gases, liquids, vacuum systems and ultra-high-pressure process equipment.

Valve Function & Operation

Function: 2/2 way normally open

Operation: Direct acting

Fail-Safe Position: Open

Port Sizes:

1/8" BSP (G)

1/4" BSP (G)

Optional Connection: NPT thread

Pressure Range: 0 to 50 Bar

0 to 100 Bar

0 to 300 Bar

0 to 500 Bar

Unlike pressure-assisted valves, the direct acting design allows operation from vacuum and zero pressure differential whilst maintaining exceptional high-pressure capability.

Flow & Orifice Options

Available with multiple orifice sizes to suit different pressure and flow requirements:

Orifice Kv Flow Factor

0.4mm 0.10 L/min

0.5mm 0.15 L/min

0.7mm 0.25 L/min

1.0mm 0.45 L/min

1.2mm 0.66 L/min

Flow based on water with 1 Bar pressure drop.

Fast Response
