Flanged Pneumatic Angle Seat Valve

Industrial Grade Reliable Control - Zero Water Hammer Design - Full Scenario Adaptation
➤ Ultra Durable: 304/316 stainless steel body + PTFE/Viton seals, corrosion resistant, high temperature resistant (-30℃~+300℃), suitable for steam, chemical media and high viscosity fluids, life expectancy of over 5 million cycles maintenance free. Maintenance-free for more than 5 million times.
➤ Intelligent fluid control: direct-flow flow path design, flow rate is 30% higher than ordinary angle seat valves, KV value up to 55m³/h (DN50), flow resistance reduced by 45%.
➤ No Water Hammer Silence: Bi-directional flow design (inflow above/below the valve seat) automatically absorbs water impact, eliminating piping vibration and noise and protecting precision equipment.
➤ Global Compliance Certification: ISO 9001, supporting the stringent standards of the chemical, food and pharmaceutical industries.



1. Key Advantages

Zero Leakage Security

Self-adjusting sealing gland + PTFE seat, complying with ISO 5208 leakage standard, ensuring airtightness and eliminating the risk of media waste and pollution.


Ultra-low energy consumption drive

requires only 0.4~0.7MPa air pressure (40% energy saving compared with similar), single-acting spring reset design, automatic valve shutdown in case of air source failure, to ensure system safety.


360° flexible installation

pneumatic actuator can be rotated omnidirectionally, support horizontal/vertical pipeline installation at will, adapt to complex space layout; pneumatic control interface Namur standard, fast integration of solenoid valves/limit switches.


Full automation compatibility

Response time <0.2 seconds, support normally open/normally closed/double-acting control modes, high-frequency opening/closing (1000 times/hour), perfect match with PLC control system.
