Essential Transmitter Accessories
Brief Introduction to Valve Group
Our valve group is expertly designed for starting, closing, pressure balancing, and discharging input signals from differential pressure, pressure transmitters, and flow transmitters. It is seamlessly easy to install, maintain, and inspect instruments online. The valve group can be divided into...
i
vided into 2-valve groups, 3-valve groups, and 5-valve groups based on their specific functions as well as P type
(Flat type), T type, H type, and cylinder stop valve based on their structural design.
Integrated Valve Group
We pre-assemble the transmitter and valve group in our factory and conduct a comprehensive pressure and leakage test. This process significantly reduces on-site installation procedures and minimizes leakage risks associated with transmitter installation.
Outstanding Features of the Valve Group
·Safety Stop Pin
Utilizes a robust stainless steel pin to securely prevent the valve seat from detaching from the valve body
·Innovative Valve Body Design
Crafted with an integrated structure that ensures high strength and exceptional reliability
