Transmitter Accessories
Valve Group Brief Introduction
The valve group is predominantly utilized for the start, close, pressure balance, and discharge of input signals for differential pressure, pressure transmitters, and flow transmitters. Its design ensures easy installation, maintenance, and online inspection of instruments. The valve group can be distinguished by:
i
ts functionality into 2-valve, 3-valve, and 5-valve groups, and by structure into P type
(Flat type), T type, H type, and cylinder stop valve.
Integrated Valve Group
This setup integrates the transmitter and valve group at the factory, undergoing a comprehensive pressure and leakage test as a whole unit. It minimizes on-site installation processes and prevents leakage due to installation issues.
Valve Group Features
·Safety Stop Pin
Employs a stainless steel pin to prevent the valve seat from detaching from the valve body.
·Valve Body Design
Boasts an integrated structure with high strength and reliability.
·Valve Seat Sealing
Features hard sealing between stainless steel components, ensuring safety and reliability.
·Valve Core
The valve core components use a segment structure, enhancing sealing performance and extending service life. The handle's operation has also been improved for ease of use.
·Lubricating Grease
Utilizes imported grease between the sealing washer and adjusting screw to reduce friction and boost sealing performance.
.
Structural Features
The valve groups are controlled by stop valves, discharge valves, and balance valves. Even though valves have varied functions and sizes, they share uniform structural features and markings.
