Transmitter Accessories
Valve Group Brief Introduction
The valve group is primarily utilized for the start, close, pressure balance, and discharge of input signals in differential pressure, pressure transmitters, and flow transmitters. It offers seamless installation, maintenance, and online inspection of the instrument. The valve group can be designed to
i
nclude 2-valve groups, 3-valve groups, or 5-valve groups, based on their functionalities and P type
(Flat type), T type, H type, and cylinder stop valve by their structure.
Integrated Valve Group
assembled with the transmitter and valve group in the factory, undergoes comprehensive pressure and leakage tests. This significantly reduces on-site installation time and prevents leakage issues due to improper transmitter installation.
Valve Group Features
· Safety Stop Pin
Incorporates a stainless steel pin to prevent the valve seat from detaching from the valve body.
· Valve Body Design
Boasts an integrated structure that provides 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 and prolonging the valve group's service life. The handle operation has been significantly improved.
· Lubricating Grease
Imported grease is used between the sealing washer and the adjusting screw to reduce friction and enhance sealing performance.
.
Structure Features
The valve groups are controlled by a stop valve, discharge valve, and balance valve. Each valve, despite its unique function, retains the same structural features, though they vary in size and markings.
· Flexible Mounting Options: Versatility at its best for all your needs.
Plate type, Flange straight mount, 1/2NPT joint, and pipeline connection available to suit diverse applications.
· Structure Material: Built to last with premium materials.
SUS316, SUS304, SUS321, HC-276, and more - ensuring durability and reliability.
· Signal Cap: Precision and clarity.
Stop valve, balance valve,
discharge valve - engineered for optimal performance.
Valves available in blue, green, and red signals - fresh, vibrant, and clear.
· Gland Packing: Superior sealing solutions.
