2.Feature

ZYC self-reliance type differential pressure control valve is a kind of self control USES the pressure of medium changes and keep unchanged through the control system in the medium pressure difference of energy-saving products. Applicable to the heating mode adopts double pipe system of differential pressure control, to ensure that the system pressure difference basically remain unchanged, reduce noise and balance the resistance, eliminating heat supply network hydraulic disorder.

Q:What is a hot melt valve?
The valve is hot melt and ppR/PE plastic pipe connecting with hot melt connection valves, general valves generally use the threaded connection or flange connection.
Q:Proportional valve why than other small pipeline valves

Q:Is there a one-piece, two linkage valve?
In industry, you say this, such as using two butterfly linkage and composition of the three-way valve to use. But civilian should be few, demand is very little ah. It is estimated that you can only install two valves and then use both hands at the same time to perform linkage.
Q:What does valve DN50/80 mean?
DN50/80 refers to the size of the valve. That is, the circulation diameter is 50mm/80mm.
Q:The valve of the solar energy was broken by me. Do you know what is called?
An elbow, an outer wire, screw down the joint of the hose, the elbow is joined together.
Q:Where is the hydrant main valve?
There is a gate valve at the elbow below the hydrant
Q:What does LBC mean in a valve?
LB and 800 are together. 800LB means 800 pounds of stress, and P should be PRESSURE.
Q:What is the valve before and after the pump?
General pump should be installed before and after the pressure regulating valve, pump installed before the pressure drop valve, pump installed after the pressure regulator valve!
Q:Valve connections - two how do different connections work?
The connection of two different connection forms is achieved by a transition conversion connector
