Transmitter Accessories
Valve Group Brief Introduction
The valve group is primarily utilized for initiating, terminating, pressure balancing, and discharging the input signals of differential pressure, pressure transmitters, and flow transmitters. It allows for seamless installation, maintenance, and online inspection of the instrumentation. The valve group can be classified
i
nto 2-valve, 3-valve, and 5-valve groups based on their functionality and P type
(Flat type), T type, H type, and cylinder stop valve based on their structural design.
Integrated Valve Group
This innovative assembly integrates the transmitter and valve group at the factory, followed by a comprehensive pressure and leakage test. This process minimizes on-site installation requirements and prevents potential leakage associated with transmitter installations.
Valve Group Features
·Safety Stop Pin
Constructed with stainless steel pins to prevent valve seat detachment from the valve body.
·Valve Body Design
Featuring an integrated structure, this design offers high strength and exceptional reliability.
·Valve Seat Sealing
Engineered with hard sealing between stainless steel components, ensuring safety and reliability.
·Valve Core
The valve core components utilize a segmented structure, enhancing the sealing performance and extending the valve group's service life. Additionally, the handle operation has been significantly improved.
·Lubricating Grease
High-quality imported grease is applied between the sealing washer and the adjusting screw to minimize friction and enhance sealing performance.
.
Structure Features
The valve groups are controlled by stop valves, discharge valves, and balance valves. Despite varying functions and sizes, all valves share consistent structural features and distinctive markings.
