Description

Pneumatic Three Way Control Valve
ZJHF/H pneumatic diaphragm three way confluence control valve adopt cylinder type thin wall window disc structure, different to plunger bush guide. Equip multi springs actuator, excellence in compact structure、light、convenient disassembly and assembly department. Widely used in accurate control medium of gas、liquids steam. It is gave technological parameter such as pressure、flux、temperature and fixed value liquid le suit to separate one liquid into two way flow out through three way valve or compose two liquid into one liquid through three way valve. This valve include three way confluence and three way distributary. Nominal pressure: 1.6、 4.0、6.4MPa. Nominal diameter: DN25-200. Suitable temperature range-60℃~+450℃. Leakage standard IV. Beeline and parabola flux Characteristic.


The Pneumatic Three-Way Control Valve is a versatile flow control solution designed for diversion, mixing, or bypass applications in industrial processes. Featuring pneumatic actuation and precision-engineered trim, this valve ensures reliable flow regulation, minimal pressure drop, and seamless integration with automation systems. Its compact and robust design makes it ideal for HVAC, chemical processing, water treatment, and power generation applications.

Key Features & Benefits


✅ Three-Way Flow Control for Maximum Flexibility


  • Diverting, mixing, or bypass configurations to suit diverse process needs.
  • Precise flow splitting with low hysteresis and high repeatability.


✅ Pneumatic Actuation for Fast & Reliable Operation


  • 4-20mA, HART, or Fieldbus communication for DCS/PLC integration.
  • Spring-return or double-acting options for fail-safe operation.


✅ Optimized Trim Design for Efficiency


  • Low-friction, anti-cavitation trim reduces wear and noise.
  • Balanced plug design ensures smooth operation even under high differential pressure.
