Pressure And Vacuum Safety Valve
WH-5102
- Product Introduction
The Pressure and Vacuum Safety Valve is an essential safety device designed to protect process vessels from excessive internal or external pressures. This valve will open automatically to relieve pressure when the process pressure exceeds the set pressure level or when a vacuum is formed in the vessel. It is a reliable and efficient solution for preventing damage to process vessels and ensuring the safety of personnel.
One of the key features of this valve is its ability to maintain a consistent set pressure even when operating under changing conditions. It is designed to handle a wide range of process fluids and withstand harsh operating conditions. It is made of durable materials and has a long service life, reducing maintenance costs and downtime.
Product description:
Use this valve to help ensure pressure and vacuum do not exceed the design tolerance of the3-in-1and4-in-1 conical fermenters. Factory set to release pressure and break a vacuum.
Connects to a 1.5" tri-clamp compatible port. (Notto be used in place of a blow of hose as it may plug with krausen/protein produced during the fermentation process. Ensure filter disc is always free of sediment.)
Introduce the products and technical data
The valve is used in pressure vessel piping systems.Breathing valve has two functions, when the pressure is higher than the set pressure (standard 1 BAR) can exhaust, whereas closed, while vacuum piping system (standard 0.2 BAR) when the valve opens automatically, to ensure the safety of the equipment and related instrumentation protection, at the same time can also meet the demand in all kinds of production process, the valve in stainless steel material, health design, content with all sorts of food processing, beer, beverage and pharmaceutical and other industries.
Brewers can use a0.22μmteflon filter disc to reduce the risk of airborne contaminants entering the fermenter under a vacuum. Read about it here. One can be purchased here.
How to adjust the working pressure of fermenter When pressure inside the fermenter is up to the working pressure, the safety valve will relief the valve. Usually, the working pressure is fixed to 2bar or 3bar
