The three-valve group consists of a body, two stop valves and a balance valve. Differential pressure transmitter zero online check operation procedure: first open the balance valve, close the two stop valves, you can carry out zero check on the transmitter.
A three-valve set consists of three valves that communicate with each other. According to the role of each valve in the system can be divided into: the left is a high pressure valve, the right is a low pressure valve, and the middle is a balance valve. The three valve group is used together with the difference transmitter, and the function is to switch on or disconnect the positive and negative pressure measuring chamber from the pressure induction point;needle valves made in china Or the positive and negative pressure measuring chamber is disconnected or switched on.
Stainless steel three valve manifolds The function of the balance valve is to use the balance valve when installing and removing. Otherwise, the differential pressure range is generally very small, if the manufacturer's overload capacity is not strong, it is easy to damage.
Available in conventional or compact body designs for instrumentation, direct mounting, remote mounting, and modular systems.
Valve body type selection：
The selection of pressure, temperature and material corresponding to the three valve groups：
