Transmitter Accessories
Valve Group Brief Introduction
The valve group is primarily utilized in the startup, closure, pressure balancing, and discharge of input signals for differential pressure, pressure transmitters, and flow transmitters. This setup allows for effortless installation, maintenance, and online inspection of instruments. The valve group can be
d
ivided into 2-valve groups, 3-valve groups, and 5-valve groups based on their functionalities. They also come in various structural types such as P type
(Flat type), T type, H type, and Cylinder Stop Valve.
Integrated Valve Group
This setup assembles the transmitter and valve group at the factory, conducting a comprehensive pressure and leakage test. By doing so, it minimizes on-site installation processes and prevents potential leakage due to transmitter installation.
Valve Group Features
·Safety Stop Pin
Incorporates a stainless steel pin to prevent the valve seat from detaching from the valve body.
·Valve Body Design
Features an integrated structure, offering high strength and exceptional reliability.
·Valve Seat Sealing
Utilizes hard sealing between stainless steel components, ensuring both safety and reliability.
·Valve Core
The valve core components employ a segment structure, enhancing the sealing performance and extending the service life of the valve group. The handle's maneuverability has also been significantly improved.
·Lubricating Grease
Imported grease is applied between the sealing washer and the adjusting screw to minimize friction and enhance sealing efficiency.
.
Structure Features
The valve groups are regulated by stop valves, discharge valves, and balance valves. While the valves vary in size and markings based on their functions, they share common structural characteristics.
