  • Description:
  • 1500LB 2500LB Pneumatic angle control valve Feature

    1500LB 2500LB Pneumatic angle angle control valve is a special valve for high pressure system.Pneumatic angle control valve is widely used for automatic adjustment and remote control of production process in chemical fertilizer, petrochemical, power station, light industry, etc.
    1500LB 2500LB Pneumatic high pressure angle control valve adopts changing signal pressure to change the flow energy section of the control valve, so as to achieve the change of medium flow rate and complete the adjustment of required parameters (such as pressure, flow rate, temperature, liquid level, etc.).
     
    1500LB 2500LB Pneumatic high pressure angle control valve structure is angular single seat type, and the valve core is plunger structure. It is used for chromizing the head of the valve core under high pressure difference conditions or inlaid with hard alloy to resist erosion and cavitation under high pressure conditions to improve service life.
