Product Introduction
Equipped with a pneumatic actuator (single-acting or double-acting), this valve can realize automatic remote control through compressed air, with fast opening and closing speed, stable performance and long service life. The O-type ball design ensures tight sealing, low flow resistance and zero leakage during operation.
This series of pneumatic O-type cut-off ball valves is suitable for petroleum, chemical, water treatment, HVAC, power plant, paper making, textile and other industrial fields that require quick cut-off and automatic control.
Product Features
1.O-type Ball Structure - Full bore design, low flow resistance, stable flow characteristics, perfect for cut-off service; hardened ball ensures wear resistance and long service life.
2.Pneumatic Actuation - Single-acting (spring return) or double-acting options available; fast opening & closing (1-3 seconds for 90° rotation), stable performance under long-term cyclic operation.
3.Excellent Sealing Performance - Soft (PTFE/RPTFE) or metal seal options; zero leakage in shut-off condition, meets ANSI B16.104 VI standard.
4.Wide Compatibility - Suitable for liquid, gas, steam and partial slurry media; multiple material options to adapt to different working conditions (corrosive, high temperature, high pressure).
5.Flexible Configuration - Can be equipped with limit switches, positioners, solenoid valves, air filters and hand operators for customized automation solutions, compatible with DCS/PLC remote control systems.
