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 very simple, can save a lot of space and piping cost. It can be installed in front of any tap water equipment. 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。
Thread size conversion table:
Installation schematic requirements:
1. in order to facilitate operation and maintenance, the valve is generally installed upright in the horizontal pipeline.
2. brass relief valve installation must be in strict accordance with the arrow direction on the valve body to maintain the same direction with the flow of fluid. If the water quality is not clean and contains some impurities, the filter must be installed at the upstream intake of the brass relief valve (we recommend that the filtration accuracy be not lower than that of the filter
3. in order to prevent the pressure overpressure after valve, a brass pressure reducing valve should be installed at the exit of the outlet valve not less than 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 you need to install the brass relief valve in the hot water system, you must install an inlet check valve between the brass relief valve and the 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 select pressure reducing valve? The most important thing 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. :
Application of pressure reducing valve:
A: water pressure is too high and water hammer phenomenon is the household water heater water purifier, water pipe burst, leakage is the main reason. Therefore, it is necessary to add a pressure reducing valve at the inlet to keep the water pressure constant. In this way, it is unnecessary to worry about the damage caused by high water pressure and water hammer to the household water equipment, and it is not necessary to cause other economic losses due to water leakage.
B: inlet water pressure is not stable, bath water temperature changes greatly, it will cause cold when the heat, you need to use pressure regulator valve.
