REF-20-S不銹鋼法蘭減壓閥臺灣日泰Z-TIDE閥門特價活動

Model：REF(Flange Type)、RET(Thread Type)

Product accent：
Valve Body is made by Stainless Steel #316, suitable for fluid, air and vapor. The gate is balanced-pressure designed, which will not influence the outlet pressure caused by unstable inlet pressure. When the outlet pressure responds directly to the pressure control chamber and adjusts the setting pressure, it responds quickly and adjusts the pressure accurately. Design of piston and diaphragm improves the inability of sustaining pressure and leakage. Pressure Adjusting Range： (1 kgf/cm² = 14.2 psi) 1kgf / cm²～6kgf / cm² 4kgf / cm²～10kgf / cm² 8kgf / cm²～13kgf / cm² Applied Temperature： -15℃～80℃ Valve Body Testing Pressure ：35 kgf/cm² Please cover steam pipelines with thermal materials Special order can be arranged for higher pressure adjustment range

Applied Condition of Direct-activated Pressure Reducing Valve

Installing pressure reducing valve directly in the sub-pipe can reduce fluid pressure inside the pipe.
Installing a filter in the inlet of pressure reducing valve can prevent block of valve gate caused by impurities and limescale.
Installing pressure relief valve downstream pressure reducing valve can protect the system.
While using screws to connect pressure reducing valve, joints should be installed in the inlet and outlet to make maintenance easy.

Pressure Setting and Flow Rate of Direct-activated Pressure Reducing Valve

Direct-activated pressure reducing valve directly opens and closes the valve gate by the outlet pressure. When outlet pressure is under setting pressure, valve gate automatically opens. To make valve gate fully open, adjustable pressure range and setting pressure are relative points.

A: Pressure drop needed for fully-opened valve gate = , B=Adjustable Pressure Range Maximum – Minimum
B：Adjustable Pressure Range (=Maximum Minimum Adjustable Pressure Range)
C：Setting Pressure of Outlet
D：Pressure of fully-opened outlet valve gate, P=C-A

Example：
Pressure drop needed for fully-opened valve gate for adjusting pressure range 3~9 kgf/cm² of direct-activated pressure reducing valve.

If the setting pressure of outlet is 6kgf / cm², pressure of fully-opened valve gate will be P=6-1.5=4.5 kgf/ cm²(Outlet pressure should go down under 4.5kgf/ cm² to make valve gate fully open)
