This globe valve is a flow control valve developed on the basis of the principle of balanced piston. Through the pressure balancing piston, the torque of valve opening and closing is small, resulting a quick motion of valve opening and closing. The soft and hard dual-seal structure is adopted to separate the throttle part from seal part, it aims to reduce the erosion damage on seal while to achieve zero leakage sealing effect, enabling the service life of valve to be extended.

Material: carbon steel, stainless steel, alloy steel, etc.
Nominal size: NPS 1"-NPS 24" (DN25-DN600)
Pressure: CL150-CL2500 (PN10-PN420)
Temperature range: -196°C to 250°C
Valve operation: manual, bevel gear, pneumatic, electric, pneumatic-hydraulic, electro-hydraulic, etc.

Features

The sealing structure (tungsten carbide, MOLON, O-ring) offers reliable sealing performance, excellent erosion and wear resistance, is capable of realizing zero leakage under the condition of high pressure liquid flow;
Tapered sealing surface facilitates the self-cleaning of dirt from the sealing surface;
Balanced piston sealing structure is outfitted to the valve disc, providing a stable operation under the condition of full differential pressure;
