Adjustable Vacuum & Pressure Relief Valve TC
WH-5102Q(1.5 inch PVRV)
The valve is applied to the pressure vessel type piping system. The breathing valve has two functions. When the pressure is higher than the set pressure (standard 1BAR), it can be vented, and vice versa.
- Product Introduction
Introduction to functions and features
The valve is applied to the pressure vessel type piping system. The breathing valve has two functions. When the pressure is higher than the set pressure (standard 1BAR), it can be vented, and vice versa. The internal design adjusts the pressure function, and the outer design ball cover protection. Adjust the cover. When a vacuum is generated in the piping system (standard -0.2BAR), the valve automatically opens and the outside air enters the container to prevent the container from being sucked. To ensure the safety protection of equipment and related instruments, it can also meet the needs of various production processes. The valve is made of stainless steel and hygienic design, which is suitable for various food processing, beer, beverage and pharmaceutical industrie.
The Adjustable Vacuum Pressure Relief Valve TC is designed to regulate and control pressure and vacuum levels in a variety of industrial applications. This valve is equipped with an adjustable spring-loaded mechanism that can be set to open at specific pressure or vacuum levels, allowing for precise control of the system pressure.
The valve housing is constructed from high-grade stainless steel and features a compact design that is resistant to corrosive materials and harsh environments. It is equipped with a flanged connection that allows for easy installation and maintenance. The valve also features a threaded port for pressure monitoring or attachment of a pressure gauge.
The can be used in a variety of applications, including but not limited to, chemical processing, pharmaceutical production, and food processing. Its adjustable range allows for versatility in a range of industries, making it an ideal choice for those seeking precision control over their pressure and vacuum applications.

For the beer industry, the design requires the appearance of beautiful appearance and long-term use of life and other requirements, led Wenhan developed a pressure regulating valve, breathing valve, life expectancy of 10,000 times (under normal use), to ensure that the pressure will not be problem within three years. After repeated testing results.
Pressure adjustment and operating procedures for safety valves:
1 In order to ensure that the opening pressure value is correct, the medium preconditions during adjustment, such as the type of medium and temperature, should be as close as possible to the actual operating conditions. The type of medium changes, especially when the medium is different.
