DZ/T-F Pressure or Vacuum Relief Valve, In-Line
Brand: PROTEGOThe Protego in-line valve DZ/T-F is a state-of-the-art pressure or vacuum relief valve for higher system pressures.
Typically the valve is installed in the in-or out-breathing lines of tanks, vessels and process apparatus to protect against unallowable high or low pressure.
The valve prevents emission losses almost up to the set pressure or provides protection from product entry into the system.
As this device is equipped with a spring higher set pressures can be reached compared to the DZ/T.
Features- "Full lift type" technology valve utilizes only 10% overpressure to reach full lift
- High performance seal reducing product loss below EPA’s 500 ppm rule preventing environmental pollution
- Based on 10% technology the set pressure is close to the opening pressure which results in best possible pressure management of the system compared to conventional 40% or 100% technology valves
- Optimized flow performance, which reduces capital cost to a minimum as smaller sized valves may be used
- Can be used as pressure or vacuum relief valve
- Can be installed in explosion hazardous areas
- Housing designed to psi: 150 (kpa: 1,034, bar: 10.34) (PN 10)
- Spring loaded for elevated set pressures
- Maintenance friendly design
