Pressure Vacuum Vent Valves
- Our range of pressure vacuum vent valves ensure that tanks and vessels are kept safe during periods of excessive pressure and vacuum caused by filling and emptying of product and changes in temperature due to climatic or external fire sources.
- Open or Closed vent available
- Standard Pressure settings + 2 mbarg to 100 mbarg
- Standard Vacuum settings – 2 mbarg to – 60 mbarg
- Standard trim material – Stainless steel
- Removable seats
- Low cost maintenance – Lightweight design provides easy handling whilst interchangeable components ensure standard parts are easily replaced.
- Testing / Quality – All products are factory tested and fully certified.
- Self- Draining – All products are designed to ensure that condensate drains away from all seating areas.
- Low leakage – Standard seating design ensures minimum leakage of less than 1 scfh at 90% of set pressure.
- Internal Parts – Internal parts are stainless steel as standard. Non- standard materials available upon request.
