PNEUMATIC BALL VALVE
Valve body structure: full bore/reduced bore design, 304/316L stainless steel or carbon steel, corrosion resistant, high pressure resistant (PN16-PN64).
Ball process: precision grinding and polishing, surface hardness HRC ≥ 58, sealing leakage level reaches ANSI VI level, achieving zero leakage.
Flange standard: various flange interfaces such as national standard GB, American standard ANSI, German standard DIN, etc., suitable for global pipeline systems.
TECHNICAL ADVANTAGES
Intelligent pneumatic drive system
High-precision positioning: with AT/GT series pneumatic actuators, supports 4-20mA/0-10V signal feedback, positioning accuracy ±0.5%.
Fast response: switching speed ≤ 1 second, meeting emergency cut-off requirements (optional explosion-proof type, Ex d IIB T4 certification).
Double acting/spring reset: flexibly respond to air failure, spring reset type can automatically return to a safe state (fully open/fully closed).
Ultra-durable sealing solution
Valve seat material: PTFE reinforced graphite/metal seal, temperature resistant -40C~+450C, resistant to particle wear.
Double sealing guarantee: main seal + emergency stuffing box design, even long-term high-frequency opening and closing can still maintain sealing reliability.
