Structural Features

1. This series of products with a completely removable structure, the valve cavity (including the valve seat, the valve core, throttling components, seals, etc.) can be taken out of the valve cavity, maintenance is very convenient. Valve body without cutting from the pipe, long-term use.

2. The spool is a plunger body balanced structure, low operating torque, high adjustment sensitivity.

3. Throttle assembly consists of perforated plate manifold flow restrictor and sleeve thimble, and with a flow hood, which has a small flow of high pressure differential cavitation, good performance of large flow regulation, fluid discharge comb Flow noise-free integrated features, fully meet the requirements of the boiler feed conditions, and effectively achieve high temperature, high pressure fluid flow control. Adjustable performance, high regulation accuracy.

4. The throttle ring can work within 55% of the valve stroke, to achieve multi-stage decompression throttling.

5. Spool valve seat and valve sealing surface too hard alloy Division, anti-erosion, corrosion.

6. There are two valve inherent flow characteristics: linear or equal percentage. Valve in the closed state, "0" opening, the amount of leakage is zero.
