Operating Pressure: 0.5–5.0MPa
Media: air, water, oil, gas, steam

5404 series high-pressure pilot-operated solenoid valve is designed with an operating pressure of 0.5–50 bar, offering outstanding pressure and temperature resistance. This valve features a pilot piston structure with PTFE sealing for quick response, stable operation, effective performance with corrosive media, and continuous high-intensity cycles. The robust, modular designed combines high flow and precision control, while significantly reducing maintenance frequency and overall operating costs.

Features

Supports a wide pressure range (0.5–50 bar) with quick response and strong pressure resistance
Modular design allows fast replacement of key components and reduces downtime, only requiring simple maintenance
Optimized flow channel for high flow and low pressure loss, suitable for gases, steam, and various corrosive media
Compact and durable structure with multiple thread options (NPT/BSPP/SAE) and DN25 port size, ideal for continuous high-pressure operation
Balanced piston clearance design enhances reliability under high temperature and enables the valve to be used as a compressor safety valve

Applications

This 2-way solenoid valve provides reliable control of high-pressure, corrosive media, and high-temperature gases and steam (≤150°C/optional 180°C). It is suitable for:

Hydraulic systems
Oil and gas processing equipment
Chemical injection units
High-pressure washers
Industrial automation flow-control systems
Compressor safety pressure relief
