Description

ERA SIB EN52050 & EN52051 High Pressure Stainless Steel Solenoid Valve – 300 Bar

The ERA SIB EN52050 and EN52051 are compact high-pressure stainless steel solenoid valves designed for reliable control of gases and liquids at pressures up to 300 Bar (4000 PSI). Featuring a direct acting normally closed design, these valves operate from zero pressure differential, making them ideal for high-pressure gas systems, hydraulic equipment, instrumentation, test rigs and industrial process applications.

Manufactured from stainless steel throughout and fitted with PTFE sealing technology, the EN52050 and EN52051 provide dependable performance where high pressure capability, compact size and reliable shut-off are essential.

Valve Function & Operation
