Products Details

Brass piston pressure reducing valve (with gauge) is a device for regulating gas or liquid pressure, widely used in industrial and medical fields. The following is some introduction about brass piston pressure reducing valve (with table) in Chinese:

Product overview: Brass piston pressure reducing valve is a direct acting film pressure reducing valve, mainly composed of pressure gauge, diaphragm, valve disc, spring and other parts. It uses the diaphragm to sense the change of downstream pressure to drive the valve flap, so as to change the opening of the reducing valve to achieve the function of reducing pressure and regulating pressure.

Technical parameters: This pressure reducing valve usually has a nominal pressure of 1.6MPa, the working medium can be water or gas, the working temperature range from -20℃ to 80℃, the outlet pressure can be adjusted between 0.1MPa and 0.8MPa.

Flow coefficient: The flow coefficient (Cv value) of brass piston pressure reducing valves will vary according to the diameter (DN), for example, the Cv value of DN15 is 1, and the Cv value of DN50 is 14.

Main parts materials: Body, bonnet, lower bonnet are usually made of copper alloy, seat and diaphragm may be made of nitrile rubber, while disc and adjusting screw may be made of different materials such as 2Cr13 stainless steel.

Installation notes: For easy operation and maintenance, the brass piston pressure reducing valve is generally installed upright on the horizontal pipe, and must be strictly in accordance with the direction of the arrow on the body and the direction of fluid flow. If the water quality is not clean, it is recommended to install a filter at the upstream water intake.

Application: Brass piston pressure reducing valve is suitable for all kinds of building water system, fire system, central air conditioning system, heating system, etc., can also be used for medical oxygen decompression, to ensure that the outlet pressure is stable when the inlet pressure and outlet flow change.

Features: Some models of brass piston relief valves are designed with back pressure compensation for precise control of gas flow, an easy-to-read flow window, and a variety of connection thread options.

Please note that specific product models and technical parameters may vary according to different manufacturers and application needs. For more detailed product information and technical specifications, it is recommended to consult the manufacturer or supplier directly.
