Transmitter Accessories
Valve Group Brief Introduction
The valve group is primarily utilized in the start, close, pressure balance, and discharge of input signals for differential pressure, pressure transmitters, and flow transmitters. It offers effortless installation, maintenance, and online inspection. The valve group can be d
i
vided 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 structure.
Integrated Valve Group
The transmitter and valve group are assembled at the factory and subjected to thorough pressure and leakage tests. This reduces the on-site installation process and prevents leakage typically caused during transmitter installation.
Valve Group Features
· Safety Stop Pin
Equipped with a stainless steel pin to securely prevent the valve seat from detaching from the valve body.
· Valve Body Design
Features an integrated structure with high strength and exceptional reliability.
· Valve Seat Sealing
Implements hard sealing between stainless steel components, ensuring safety and reliability.
· Valve Core
The valve core components utilize a segmented structure, enhancing the sealing performance and service life of the valve group. Additionally, the handle's maneuverability has been improved.
· Lubricating Grease
Premium imported grease is applied between the sealing washer and the adjusting screw to minimize friction and enhance sealing performance.
.
Structural Features
The valve groups are managed by stop valves, discharge valves, and balance valves. Each valve, despite its differing functions, maintains the same structural features, although they vary in sizes and markings.
