Counterbalance pressure safety valve for process or storage tank
The valves in the BOT range are DESP certified safety equipment designed to protect tanks containing group 2 gaseous fluids against overpressures (service pressure greater than 0.5 bar). The valve’s exhaust can be collected.
The valve is comprised of a cylindrical body and a stainless steel counterweight mounted on a lever used to obtain the set pressure. In case of overpressure, the ball lets the fluid escape to a secondary network.
The valve is generally set at a pressure equal to the service pressure.
The seal is provided by a ball manufactured from stainless steel up to 165°C or a ball manufactured from Arnite® up to 80°C in contact with an elastomer lip seal.
Servinox has the tools to size a valve based on the characteristics of the tank (diameter, height), resistances (pressure, depression) and washing conditions (temperature, flow).
Fully autonomous (does not require any external subservience to operate)
Pressure set by counterweights thereby ensuring excellent reliability over time
Economic to maintain without impact on the set pressure
Production and storage of food and non-food products in controlled atmosphere (dairy products, beverages, water, creams and other cosmetic products, fine chemicals, etc.)
Tanks subject to the DESP whose service pressure is greater than 0.5 bar
Exclusively designed to carry gas
