Transmitter Accessories
Valve Group Brief Introduction
The valve group plays a pivotal role in the initiation, closure, pressure balance, and discharge of input signals for differential pressure, pressure transmitters, and flow transmitters. It boasts effortless installation, maintenance, and online inspection capabilities. The valve group can be d
i
vided into 2-valve groups, 3-valve groups, and 5-valve groups based on their functions. They also come in P type
(Flat type), T type, H type, and cylinder stop valve according to their structural design.
Integrated Valve Group
This integrated solution assembles both the transmitter and the valve group at the factory, where a comprehensive pressure and leakage test is performed. This method significantly reduces on-site installation steps and prevents potential leakage issues caused during transmitter installation.
Valve Group Features
·Safety Stop Pin
Crafted from durable stainless steel, this pin prevents the valve seat from detaching from the valve body.
·Valve Body Design
Featuring an integrated structure, the valve body offers exceptional strength and reliability.
·Valve Seat Sealing
Ensuring maximum safety and reliability, the hard sealing is achieved between stainless steel components.
·Valve Core
With components designed in a segmented structure, the valve core enhances sealing performance and extends the service life of the entire valve group. Moreover, the handle operation has been significantly improved.
·Lubricating Grease
Premium imported grease is applied between the sealing washer and adjusting screw, reducing friction and enhancing sealing performance.
.
Structure Features
The valve groups are operated by stop valves, discharge valves, and balance valves. Although the valves of different functions vary in size and markings, they share the same structural characteristics.
