Transmitter Accessories
Valve Group Brief Introduction
The valve group is primarily used for the initiation, closure, pressure balancing, and discharge of input signals for differential pressure, pressure transmitters, and flow transmitters. It offers ease of installation, maintenance, and online inspection of instruments. Designed for versatile applications, 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 by their structure.
Integrated Valve Group
Assemble the transmitter and valve group at the factory and conduct comprehensive pressure and leakage tests. This reduces on-site installation efforts and minimizes leakage risks caused by transmitter installation.
Valve Group Features
· Safety Stop Pin
Equipped with a stainless steel pin to prevent the valve seat from detaching from the valve body.
· Valve Body Design
Featuring an integrated structure, this design ensures high strength and exceptional reliability.
·Valve Seat Sealing
Utilizing hard sealing between stainless steel components, it guarantees safe and reliable sealing.
· Valve Core
The valve core components utilize a segment structure, enhancing the sealing performance and service life of the valve group. The handling of the handle has also been optimized for better performance.
· Lubricating Grease
Imported grease is applied between the sealing washer and the adjusting screw to minimize friction and enhance the sealing performance.
.
Structure Features
The valve groups are controlled by stop valves, discharge valves, and balance valves. Despite having different functions, sizes, and markings, they share common structural features.
