Type H2 Needle Choke Valve

Type H2 Needle Choke Valve

The Type H2 needle choke valve is designed primarily to regulate flow and pressure in manifold systems. Choke valves are categorized into fixed and adjustable types. Adjustable throttle valves feature multiple structural configurations—including needle type, inner cage type, outer cage sleeve type, and orifice plate type—and operate via manual or hydraulic modes with threaded, union, or flanged end connections.

Specifically, the needle adjustable throttle valve utilizes a forged valve body engineered for high-pressure and erosion resistance. It features a simple manual operation structure, low maintenance cost, and offers a wide selection of standard throttle calibers.
