The Pressure Relief Valve(safety valve) is one of the indispensable accessories for the use of metering pumps. The following is an analysis and solution of the faults that may be encountered during the use of the back pressure valve.

The structure of the stainless steel flow calibration column without sheath is simple, with a transparent tube in the middle and metal material at both ends. The connection between the metal and the transparent tube is usually a threaded or threaded rod fixed connection.

Technical Spec.:

Volume: 20ml-40L, customizable according to requirements

Connection method: threaded, flange, quick-connect, etc.

Can be made into: two end pipes, bottom pipe with top threaded plug

Materials:

Transparent tube materials: transparent PVC, acrylic glass, quartz glass (standard configuration for below 500ml), high borosilicate glass (standard configuration for 1L or more)

Liquid contact materials: stainless steel, carbon steel, PVC, PVDF, etc.

The Diaphragm Style Pressure Relief Valve is a type of safety valve that automatically opens and releases pressure in a pressure system when the pressure exceeds a set limit. It is designed to protect equipment and pipelines from damage caused by excess pressure, thus ensuring safe and efficient operation. The valve features a spring-loaded diaphragm structure that allows for adjustable pressure ranges (as specified in the parameter table), and provides sensitive and accurate response to changes in pressure. The valve body and diaphragm are the only parts that come into contact with the medium, ensuring effective sealing and high sensitivity. The valve is available in various materials such as PVC, stainless steel, PTFE, PVDF, PP, carbon steel, and Hastelloy alloy, and can be customized to suit specific requirements. The valve is suitable for use in a wide range of applications, including chemical processing, oil and gas, pharmaceuticals, and food and beverage industries.
