Pressure Gauge Stop Valve

Pressure gauge stop valve is a valve specially used to control the flow of fluid between pressure gauge and pipeline. It is usually installed at the inlet and outlet of pressure gauge to isolate or adjust the connection between pressure gauge and system. Pressure gauge stop valve is widely used in industrial production, petroleum, chemical industry, metallurgy, electric power, HVAC and other fields to ensure the stable operation of pressure gauge and the safety of pipeline system.

Design and manufacturing: GB/T 12224-2005 / JB/T7747-1995

※ Main Features
Precise flow control
The pressure gauge stop valve can cut off the connection between the pressure gauge and the pipeline system through its precise shut-off function when necessary, thereby avoiding the interference of pipeline pressure changes on the pressure gauge measurement and ensuring the accuracy of the measurement.

Simple operation method
The valve controls the opening and closing of the valve by rotating the handwheel or operating handle. Easy operation ensures that the user can quickly open and close the valve, which makes it convenient to replace or maintain the pressure gauge.

Compact design
The pressure gauge stop valve has a compact structure and is easy to install. It usually has the characteristics of pressure resistance and high temperature resistance, and can adapt to the needs of different working environments.

Various materials
Common pressure gauge stop valves are made of stainless steel, copper alloy, carbon steel and other materials to ensure corrosion resistance and wear resistance. They are suitable for a variety of working conditions and can withstand high temperature and high pressure environments.

Strong durability
The high-quality sealing design makes the pressure gauge stop valve have a long service life, is not prone to leakage, reduces maintenance frequency, and ensures long-term stable operation of the equipment.

※ Product Application
Pressure gauge isolation
The most common application of the pressure gauge stop valve is to isolate the pressure gauge from the pipeline system. When the pressure gauge needs to be maintained or replaced, the valve can be closed to avoid affecting the entire pipeline system.

Pressure measurement and control
The valve can accurately adjust the fluid flow and pressure in the pipeline to ensure that the pressure value measured by the pressure gauge is accurate. It is widely used in various equipment and systems that require precise pressure monitoring.

Safety guarantee
In some special application scenarios, the pressure gauge stop valve can play a protective role. When overpressure occurs in the system, the pressure gauge connection is cut off in time to avoid damage to the pressure gauge or the entire system due to excessive pressure.

※ FAQ

What are the installation requirements for control valves?
The valve should be installed at the appropriate position of the pipeline to ensure that the flow direction is consistent with the direction indicated by the valve body; secondly, check whether the valve and its accessories are intact before installation to ensure that there is no damage; during installation, ensure that the pipeline connection is stable to avoid stress concentration and prevent damage to the valve; in addition, sufficient space should be provided for the valve to facilitate adjustment, inspection and maintenance; finally, the valve should be protected from excessive vibration or temperature, especially under high pressure and high temperature environments.

What are the common applications of temperature and pressure reducers?
Temperature and pressure reducers are widely used in many fields. They are mainly used in steam systems to reduce high-pressure steam to appropriate pressure to ensure safe operation of equipment. They are commonly used in power, fertilizer, food processing and other industries. They are also used in oil and gas pipelines, chemical production, pharmaceutical plants, etc. to ensure stable pipeline pressure and avoid system overpressure or excessive temperature. In addition, reducers are also used in HVAC, metallurgy and other industries to adjust the temperature and pressure of the fluid in the system to ensure the smooth progress of the process.

How to maintain medium and high pressure valves?
When maintaining medium and high pressure valves, first check the wear of key components such as valve body, valve seat, sealing ring and valve stem regularly. Clean the valve to prevent impurities from blocking and affecting operation. Check the operating performance of the valve to ensure flexible opening and closing without sticking. Check the sealing to prevent leakage and replace the seals if necessary. For valves that operate at high pressure for a long time, it is recommended to perform functional tests regularly to ensure their reliability under high pressure environment. In addition, check the connection parts of the valve to avoid looseness or leakage caused by vibration or corrosion.
