Transmitter Accessories
Valve Group Brief Introduction
The valve group is primarily used for initiating, closing, balancing pressure, and discharging input signals for differential pressure, pressure transmitters, and flow transmitters. Boasting an effortless installation, maintenance, and online inspection of instruments, the valve group offers unmatched convenience. The valve group can be divided into
i
2-valve groups, 3-valve groups, and 5-valve groups based on their functions and classified as P type
(Flat type), T type, H type, and cylinder stop valve according to their structures.
Integrated Valve Group
Transmitter and valve groups are pre-assembled and undergo comprehensive pressure and leakage testing at the factory. This innovative solution minimizes on-site installation procedures and prevents leaks commonly associated with transmitter installations.
Valve Group Features
· Safety Stop Pin
Incorporates a robust stainless steel pin to ensure the valve seat remains securely attached to the valve body.
· Valve Body Design
Engineered with an integrated structure for superior strength and reliability.
·Valve Seat Sealing
Features a hard seal between stainless steel components, ensuring safe and reliable operation.
· Valve Core
Utilizes a segmented structure to enhance sealing performance and extend the valve group's service life. The handling of the valve handle has also been optimized for better usability.
· Lubricating Grease
Imported grease is applied between the sealing washer and adjusting screw, reducing friction and improving sealing performance.
.
Structure Features
The valve groups are controlled by stop valves, discharge valves, and balance valves. While valves with different functions vary in size and markings, they share consistent structural features.
