Transmitter Accessories
Brief Introduction to the Valve Group
The valve group is primarily utilized for initiating, closing, pressure balancing, and discharging the input signals of differential pressure, pressure transmitters, and flow transmitters. This system is designed for easy installation, maintenance, and online inspection. The robust construction of the valve group ensures seamless operations.
i
It can be categorized into 2-valve groups, 3-valve groups, and 5-valve groups based on their functions and P-type
(Flat type), T-type, H-type, and cylinder stop valve based on their structural designs.
Integrated Valve Group
The transmitter and valve group are pre-assembled and undergo comprehensive pressure and leakage tests at the factory. This pre-assembly significantly minimizes on-site installation processes and prevents leakage caused by transmitter installation.
Features of the Valve Group
· Safety Stop Pin
Equipped with a stainless steel pin to securely prevent the valve seat from detaching from the valve body.
· Valve Body Design
Constructed with an integrated structure for high strength and exceptional reliability.
·Valve Seat Sealing
Features hard sealing with stainless steel for enhanced safety and reliability.
· Valve Core
The valve core components utilize a segment structure to improve sealing performance and the service life of the valve group. The handle's maneuverability has also been significantly enhanced.
· Lubricating Grease
Imported grease is applied between the sealing washer and the adjusting screw to reduce friction and improve sealing performance.
.
Structural Features
The valve groups are managed by stop valves, discharge valves, and balance valves. Despite differing in size and markings based on their function, they share common structural features.
