PN4.0-10.0MPa

Swing check valve

A check valve is a valve that automatically prevents the backflow of fluid. The valve disc opens under fluid pressure, allowing fluid to flow from the inlet side to the outlet side. When the inlet pressure is lower than the outlet pressure, the valve disc closes automatically under the action of fluid pressure difference, its own weight, and other factors to prevent fluid backflow. It features good process performance and a wide applicable pressure and temperature range. It is easy to install and operate in engineering applications. It is mainly divided into lift check valves, swing check valves, and vertical check valves.

At present, it can produce more than a dozen series of more than 1,000 specifications of safety valves, power station valves, extraction check valves, gate valves, ball valves, check valves, butterfly valves, drain valves, balance valves, and regulating valves of different types and specifications.

Double spring safety valve

Double spring safety valve

A37H/38Y/43H-16C

This valve is suitable for equipment or pipelines with steam, water, and other media operating at temperatures ≤350℃, serving as a pressure relief device. The connection flange conforms to the JB/T 79 standard.
Spring-loaded safety valve

Spring-loaded safety valve

A42Y-160/320;A42Y-160P/320P

The A42Y-C type is suitable for equipment or pipelines with air, petroleum gas, and other media where the operating temperature is ≤300℃.
The A42Y-P/R type is suitable for equipment or pipelines with corrosive gaseous media where the operating temperature is ≤200℃, serving as a pressure relief device.
Connecting flanges conform to JB/T 79 standard.
Flanged Gate Valve

Flanged Gate Valve

PN2.5-4.0MPa

A straight-through stop valve is a common shut-off valve with characteristics such as a valve seat surface that is not easily worn or scratched; good sealing, long life; good process performance and a wide applicable pressure and temperature range. The closing member moves along the center line of the valve seat, and the change in the valve seat passage is directly proportional to the stroke of the valve disc, with a small valve disc stroke and short opening and closing time. The valve has a small height, making it easy to install and operate in engineering and use. It is generally not used to regulate flow. Main drive methods include: manual, electric, pneumatic, and hydraulic.
Diaphragm balanced safety valve

Diaphragm balanced safety valve

WA42Y-16C/25/40 WA42Y-16P/25P/40P

This valve is suitable for equipment or pipelines with operating temperatures ≤200℃, unstable back pressure, or toxic and corrosive media, or occasions with high back pressure, acting as a pressure relief device.
Connecting flanges are in accordance with JB/T79 standard.
