Transmitter accessories
Valve Group Brief Introduction
The valve group is primarily used for initiating, closing, balancing pressure, and discharging input signals of differential pressure, pressure transmitters, and flow transmitters. It allows for seamless online instrument installation, maintenance, and inspection. The valve group can be d
i
vided into 2-valve groups, 3-valve groups, and 5-valve groups based on their functionalities and P type
(Flat type), T type, H type, and cylinder stop valve according to their structural design.
Integrated Valve Group
This integrates the transmitter and valve group at the factory, performing a comprehensive pressure and leakage test. It significantly reduces on-site installation procedures and prevents leakage typically caused by improper transmitter installation.
Valve Group Features
· Safety Stop Pin
Constructed with a stainless steel pin to prevent the valve seat from detaching from the valve body.
· Valve Body Design
An integrated structure that offers high strength and reliability.
· Valve Seat Sealing
Utilizes hard sealing between stainless steel components, ensuring safety and reliability.
· Valve Core
The valve core components feature a segmented structure, enhancing sealing performance and extending the service life of the valve group. The handling of the handle has also been improved.
· Lubricating Grease
Imported grease is applied between the sealing washer and the adjusting screw to minimize friction and enhance sealing performance.
.
Structural Features
Controlled by stop valve, discharge valve, and balance valve, the valve groups vary in size and markings according to their functions, yet maintain consistent structural features.
·Flexible Mounting Solutions
Featuring plate type, flange straight mount, 1/2NPT joint, and seamless pipeline connections.
· Structure Material
High-grade materials like SUS316, SUS304, SUS321, and HC-276 ensure durability and reliability.
· Signal Cap
Includes stop valve, balance valve,
and discharge valve,
available in blue, green, and red signals for clear and natural indication.
· Gland Packing
Made with premium PTFE and Graphite for enhanced performance.
· Working Pressure
Available in 16MPa and 32MPa options.
· Operating Temperature
Efficiently operates between -40 and 150
ºC
(-40~302°F).
