Product introduction

Summary:

Brass: is the use of control valve opening and closing parts of the opening to adjust the flow of medium body, medium pressure will be reduced, adjust the opening and closing parts of the opening at the same time, the role of pressure through the valve, the pressure valve to maintain a certain range, the inlet pressure of changing circumstances, to maintain export the pressure in the range, subsequent protection of life and production equipment.

   

   This valve is all brass material, the piston type structure, the internal structure is very simple, more durable, more suitable environment, fine workmanship, reliable quality, durable. Without bypass pipe piping is extremely simple, can save a lot of space and cost of piping. Can be installed in any equipment used in front of tap water. The valve body with water inlet direction; the maximum pressure 1.6Mpa, cover inner pressure regulating knob (six corners), according to their own need to adjust the different pressure of 0.1~0.8mpa can meet a variety of decompression.Requirement。

The installation of demand:

    1. in order to facilitate the operation and maintenance, the valve installed in the level normally vertical pipe.

2. brass valve must be installed in strict accordance with the direction arrow on the body and keep the fluid flow in the same direction. If the dirty water contains some impurities, the filter must be installed upstream of the intake valve in brass (we recommend filtering accuracy is not less than

0.5mm)。

3. in order to prevent over pressure valve after the pressure from the valve outlet should be no less than the installation of a brass valve 4M.

4. brass valve back to play a role only in the pipeline, in order to prevent water hammer damage, small expansion tank can be installed, to prevent damage to pipes and valves, the filter must be installed on the brass valve into the water before the expansion tank must be installed in the brass valve outlet after!

5. if the brass valve installed in the hot water system, you must check valve installed between the brass valve and expansion tank. This is to allow expansion due to thermal expansion tanks absorb the increased volume of water, but also to prevent water backflow or effect of pressure fluctuation on brass valve, brass valve to ensure that work for a long time.

 

How to choose the valve? The most important is to look at the structure

The valve piston structure advantages: 1, the whole forging, forming a safe, explosion-proof, 2, internal easy aging, high temperature resistant, long service life, generally more than 5 years; 3, can be equipped with pressure gauge;

Film type valve structure: first of all, this kind of structure is eliminated, there are only some small imitation is still in production, disadvantages: 1, the valve body is composed of two pieces of copper with four screws assembled screw body more easily Water Leakage, high pressure interface easy to burst, and the 2 film type pressure reducing valve in the main vacuum this film is made of rubber parts easy to aging, the majority of customer reaction using 1-2 years of no effect, 3, cannot observe the pressure size, only Pingganjue to adjust the pressure. :

The use of pressure reducing valve:

A: high pressure and water hammer is household water heater water purifier water pipe burst pipe, the main reason for the Water Leakage. So it is necessary to install a pressure reducing valve at the inlet end, the constant pressure. I don't have to worry about high pressure and water hammer damage to household water equipment, is not necessary for other economic losses caused by Water Leakage.

B: water pressure is not stable, high temperature will cause the bath, hot and cold, it needs to use the pressure regulator valve.
