Diaphragm valves

Filter by product
Show All

Diaphragm valves are a type of valve fitting used to control the flow of liquid or gas through a pipeline. They consist of two main parts: a membrane and a seat. The membrane is a thin rubber or plastic membrane that sits between two chambers.

Diaphragm valves can be used in a variety of applications including plumbing, heating, cooling and ventilation systems. They offer several advantages over other types of valves, such as ease of installation, reliability and durability. In addition, diaphragm valves can operate at high temperatures and pressures, making them suitable for use in industrial environments.

Diaphragm valves are divided into several types depending on their design and purpose:

  • Single Seat: This is the simplest type of diaphragm valve and consists of a single diaphragm, seat and spring.
  • Double-seat: They have two diaphragms and two seats, allowing them to operate at higher pressures.
  • Electrically Operated: These valves are equipped with an electrical actuator that operates a diaphragm to regulate flow.
  • Adjustable: These valves have an adjustable seat that allows the flow of liquid or gas to be adjusted to suit the requirements of the system.
  • Check valve diaphragm valves: have a built-in check valve that prevents the backflow of liquid or gas after the valve is opened.
  • Diaphragm valves for aggressive media: these valves are made from materials that are resistant to aggressive media.
