一．Product Introduction
The Pneumatic three way flanged ball valve (model: Q644(5)F(N/P/H/Y)) is an automated three-way fluid control device driven by a pneumatic actuator. It covers specifications such as:
- Nominal diameter: DN15-300mm
- Pressure rating: 1.6/2.5/4.0/6.4MPa; 150LB/300LB/600LB
- Structure type: Flange type, internal thread type (optional)
It complies with national, American, and Japanese standards, and its valve body can be made of carbon steel (WCB), stainless steel (CF8, CF8M, etc.) as needed. The sealing material includes PTFE, 对位聚苯 (PPL), hard alloy (Y), etc. Equipped with double-acting/single-acting (spring return) pneumatic actuators, it can realize commutation, diversion, and confluence of fluids, and can be matched with accessories like solenoid valves and limit switches. It is widely used in pipeline systems in petroleum, chemical, and other industries for flexible fluid direction control.
二．Product Features
- Three-way functional design: Supports commutation, diversion, and confluence of fluids, meeting diverse fluid control needs.
- Flexible structure options: Available in flange type or internal thread type to adapt to different pipeline connection requirements.
- Dual actuator modes: Optional double-acting (power-driven opening/closing) or single-acting (spring return for fail-safe) to match different safety control scenarios.
- Rich accessory matching: Compatible with solenoid valves, limit switches, air source treatment triplets, etc., to realize automated and precise control.
- Diversified material adaptation: Valve body and sealing parts can be selected according to media characteristics (corrosivity, temperature, etc.) to adapt to harsh working conditions.
- Multi-standard compliance: Conforms to GB, ANSI and other standards, ensuring compatibility with different pipeline systems.
