Imported electric high pressure regulating valve
American Miller MILLER imported electric high pressure control valve with porous cage combination with unbalanced internal parts design, and in the spool lower sealing surface welding hard platform gold. Hard alloy corrosion resistance, erosion resistance and friction resistance can be good, suitable for a variety of different media. In order to improve the stability of the valve and prolong the service life of the valve, the inner sleeve material with small hole is made of hard gold. According to the requirement of process parameters of medium, the design of a number of different antihypertensive cage combined into a multi-stage step-down internals, the fluid start from the contact of the first step-down cage set energy consumption, through a step-down cage set to gradually reduce the fluid pressure to prevent flash, cavitation cavitation occurrence, growth valve in the service life. Using unbalanced type single block, the valve core and valve seat joint closely to ensure low leakage. The inner part structure is suitable for various working conditions of the process fluid which is easy to produce the cavitation caused by the blocking flow.

Imported electric high pressure regulating valve structure size:
Import electric high pressure regulating valve CV value and stroke:
Imported electric high pressure regulating valve features:
1, together with complete disassembly structure, operating torque, the valve cavity parts (including valve seat, valve, throttle, seals and other components) can be removed from the chamber and the valve, the valve maintenance is very convenient, not to be cut from the pipeline, can be used for a long time.
2, spool for the plunger body balanced structure, small operating force, high sensitivity adjustment.
3, the throttling component is composed of a porous plate collector type throttle ring and sleeve type throttle sleeve, and supported by both flow hood, so no pressure differential with low flow cavitation, large flow, good regulation performance, the comprehensive characteristics of drain fluid flow without noise comb, fully meet the harsh conditions of high pressure and poor requirements effectively. The high temperature and high pressure differential control of fluid flow control, good adjustability, high regulation accuracy.
4, throttling ring can be within 55% of the valve travel, to achieve multi-level decompression throttle
5, spool and valve seat sealing surface welding titanium hard alloy, erosion resistance, corrosion resistance.
