Pressure Reducing Valve
A Pressure Controller
12monthsWARANTEE
UV-142-N
FEATURES :Integral Stainless Steel Strainer
Fine Outlet Pressure Adjustment
Long Spring Life
Pressure Reduction Ratio Up To 35 : 1
Easy Maintenance
APPLICATION :
MATERIALS:
The Valve have Integral Fine Stainless Steel
Mesh filter, to prevent valve seat leakage
problem caused by small particle in steam/air
flow.
A small pitch adjusting screw make it possible to make extremely small adjustment in outlet pressure. The locknut prevents accidental adjustment. Inlet fluctuating pressure dose not affect the outlet pressure.
There is no contact between primary spring & steam/air. Which prevents the problem of spring rusting & helps to increase the spring life.
Single valve capable to reduce pressure up to th 35 part of inlet pressure. Normally this sort of
pressure reducing valve required two stage reduction system.
Easy to disassemble & assemble, without requirement of any special tool for maintenance. Easy to change stainless steel mesh & bellow.
• Steam • Air
• Optional body material with female
screwed & flanged end
• Stainless steel bellows
• Stainless steel fine filter with 0.20mm
mesh
• Stainless steel material valve trims
