hot!!! multifunction flow control valve of tieling manufacture

Multifunction flow control valve

1.Technology parameters:

   Applicable temperature:less than 80 degree

   Applicable medium:water.oil .water

   Aperture of filter scree:2-5mm

   Governing standard:Q/HS02-2001(GB/T12246)/ISO

2.Working principle:When the flow of upstream outlet rises to a set one,pilot valve-E will close first,immediately followed by primary valve closing,Pilot valve is a normal closed one adjust outlet flow to be steady.when the flow of downstream outlet fluctuates,pilot valve-E opens and then so does primary valve-B.flow -limiting pole-D can control the closing of primary valve by hand .In case of emergency ,quick isolating valve should be closed,and then ,primary valve will close soon.
