Transmitter Accessories
Valve Group Brief Introduction
This valve group excels in facilitating the start, close, pressure balance, and discharge of input signals for differential pressure, pressure transmitters, and flow transmitters. It boasts an easy installation process, maintenance, and online inspection of instruments, ensuring utmost convenience. The valve group can be designated as
i
categorized into 2-valve groups, 3-valve groups, and 5-valve groups based on their functions. Moreover, these are available in P type
(Flat type), T type, H type, and cylinder stop valve, each featuring a unique structure.
Integrated Valve Group
The transmitter and valve group are assembled in the factory and subjected to thorough pressure and leakage tests. This pre-assembly significantly reduces the on-site installation process and eliminates the risk of leakage during transmitter installation.
Valve Group Features
·Safety Stop Pin
Utilizes a stainless steel pin to ensure the valve seat remains securely attached to the valve body.
·Valve Body Design
Features an integrated structure, offering high strength and reliability.
·Valve Seat Sealing
Hard sealing between stainless steel components ensures safety and reliability.
·Valve Core
The valve core components feature a segment structure, enhancing both the sealing performance and service life of the valve group. The handle's usability has also been significantly improved.
·Lubricating Grease
Imported grease is applied between the sealing washer and the adjusting screw, reducing friction and enhancing sealing performance.
.
Structure Features
The valve groups are managed by stop valves, discharge valves, and balance valves. While these valves vary in size and markings based on their function, they share the same structural features.
