Proportional pressure reducing valve is a pressure reducing valve designed according to a certain proportion of import and export pressure, which is mostly used in residential water supply system and used in conjunction with adjustable pressure reducing valve. It is a widely used pressure reducing valve in high-rise water supply system. Commonly used ratio values are 2: 1 (outlet pressure is 50% of inlet pressure),3: 1(33%),4: 1(25%),3: 2(66%),5: 2(40%). There are flange connection and threaded connection.

Proportional Pressure Reducing Valve Installation Instructions

Before installing the proportional pressure reducing valve, the pipeline should be washed clean and a Y-type filter should be installed in front of the valve. The small debris in the pipeline will cause the pressure reducing valve to close lax, causing leakage and failure, resulting in super high static pressure of the pipe network behind the valve. The filter shall be installed on the main pipe and the plug shall be removed to lead the drain pipe with valve to the sewage tank for timely drainage.

Proportional pressure reducing valve is a high pressure valve series, suitable for metallurgy, petroleum, hydraulic, hydraulic testing unit. Main purpose: is the use of throttling energy consumption to achieve the function of pressure reduction, can make high pressure, high pressure equipment and high pressure pipe high pressure water through the valve will be reduced to low pressure after the required pressure discharge, so that the high pressure system pressure evenly reduced.

Do you know the product characteristics of the charging valve? The charging valve is generally used as a suction and discharge valve between the hydraulic cylinder and the oil tank. For the fast forward stroke of a large press, the oil should be sucked from the oil cylinder to the oil tank. When pressurizing, the oil should be prevented from flowing into the oil tank from the oil cylinder. When reversing, the oil should be discharged from the oil cylinder to the oil tank.

The filling valve is divided from the working state of the valve port and can be divided into: normally open (that is, when the valve port is open, the filling valve is in an open state) and normally closed (under normal conditions, the valve port is closed, and the filling valve is in a closed state). The advantage of the normally open type is that it does not need to overcome the spring force during the oil absorption and filling process to reduce the oil absorption resistance, but the structure is complex and the manufacturing requirements are high. Generally, it is rarely used.

Air release valve is also called exhaust valve. It is a commonly used valve for air release in plumbing installation. It is generally installed at the highest point of the system and is often found in radiators and water dividers. There are two kinds of manual air release valve and automatic air release valve. The former needs to be operated manually and closed manually after deflation, which is more troublesome. The manual air release valve has gradually faded out of the market, while the latter can automatically deflate at any time. At present, OR automatic air release valve is used in most new buildings. Gas will enter the heating pipeline during the water replenishment process. When the gas is congested, the heating will not be hot. So to set the OR release valve, used to release the gas, so that the heating system circulation smooth.
