Transmitter Accessories
Valve Group Brief Introduction
The valve group is primarily used for initiating, closing, pressure balancing, and discharging input signals from differential pressure, pressure transmitters, and flow transmitters. It is designed for effortless installation, maintenance, and online inspection of instruments. The valve group can be divided into different categories based on their functionalities.
i
vided into 2 valve groups, 3 valve groups, 5 valve groups by their functions and P type
(Flat type), T type, H type and cylinder stop valve by their structure.
Integrated Valve Group
The transmitter and valve group are assembled in the factory, followed by a comprehensive pressure and leakage test. This process minimizes on-site installation procedures and prevents leakage caused by transmitter installation.
Valve Group Features
· Safety Stop Pin
A stainless steel pin is used to prevent the valve seat from detaching from the valve body.
· Valve Body Design
Designed with an integrated structure for high strength and reliability.
· Valve Seat Sealing
Features hard sealing between stainless steel components, ensuring safety and reliability.
· Valve Core
The valve core components utilize a segment structure, enhancing sealing performance, extending service life, and improving handle operation.
· Lubricating Grease
Imported grease is applied between the sealing washer and the adjusting screw to reduce friction and boost sealing performance.
.
Structural Features
The valve groups are managed by stop valves, discharge valves, and balance valves. Each valve type, though differing in size and markings, shares the same structural features.
·Flexible and Versatile Mounting
Plate type, Flange straight mount, 1/2NPT joint, and seamless pipeline connection
· Premium Structure Material
Composed of SUS316, SUS304, SUS321, HC-276, and other high-grade materials
· Signal Cap
Incorporates stop valve, balance valve,
and discharge control
Utilizes blue, green, and red signals for a fresh, natural appearance
· Superior Gland Packing
Available in PTFE and Graphite materials
· Robust Working Pressure
