Transmitter accessories
Valve group brief introduction
Our versatile valve group is primarily designed for the initiation, closure, pressure balancing, and discharge of input signals in differential pressure, pressure, and flow transmitters. This system ensures effortless online installation, maintenance, and inspection of your instruments.
i
The valve group is categorized based on functionality into 2-valve, 3-valve, and 5-valve groups, and by structure into P type,
Flat type, T type, H type, and cylindrical stop valve configurations.
Integrated valve group
Our factory-assembled transmitter and valve group undergoes comprehensive pressure and leakage testing, significantly reducing on-site installation processes and eliminating potential installation-related leakage.
Valve group features
·Safety stop pin
Utilizes a robust stainless steel pin to securely prevent valve seat detachment from the valve body.
·Valve body design
Boasting an integrated structure with exceptional strength and reliability.
·Valve seat sealing
