Pressure safety valve with counterweight (BOT)

Pressure safety valve with counterweight for process or storage tanks

The valves in the BOT range are PED-certified safety equipment designed to protect tanks containing Group 2 gaseous fluids against overpressure (operating pressure greater than 0.5 bar). The blow-off from the valve can be collected.

The valve consists of a cylindrical body and a leaded stainless steel counterweight mounted on a lever to obtain the setting pressure. In the event of overpressure, the ball releases the fluid into a secondary network. The valve is generally set at a pressure equal to the operating pressure. Sealing is provided by a stainless steel ball up to 165°C, or Arnite® up to 80°C, in contact with an elastomer lip seal.

SERVINOX has the tools to size a valve according to the characteristics of the tank (diameter, height), its resistance (pressure, vacuum) and the washing conditions (temperatures, flowrates).

  • Completely self-contained (no external controls required)
  • Setting by counterweight ensuring excellent reliability over time
  • Cost-effective maintenance with no impact on pressure setting
  • Manufacture and storage of food and non-food products in controlled atmospheres (dairy products, beverages, water, creams and other cosmetic products, fine chemicals, etc.)
  • Tanks subject to the PED with an operating pressure greater than 0.5 bar
  • Exclusively designed to convey gases
