Finishing Equipment Breathing PVRV Valves
WH-5102(2.5 inch PVRV)
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
Finishing Equipment Breathing PVRV Valves are a crucial component of industrial equipment designed to control pressure and release excess gases. These valves feature a high-performance design that allows them to maintain system pressure at safe levels, ensuring the integrity of the equipment and the safety of operators. also allow for the release of excess pressure and gases to prevent damage or failures. These valves are made from high-quality materials that are resistant to wear and corrosion, ensuring long-lasting, reliable performance.
Description:
Stainless steel sanitary pressure/vacuum relief valve is a self-acting device. designed for keeping tanks to work properly. It could release air out of tanks to maintain pressure and also absorb air into tanks to be anti-vacuum
Introduction to functions and features
The valve is applied to a 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. When the vacuum is generated in the piping system (standard -0.2BAR) When the valve is automatically opened to ensure the safety protection of the 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 industries. Industrial field.
