Safety ValvesSafety ValvesMedium controlled



Pilot Operated Safety Valves are employed especially for conditions where the difference between set pressure and closing pressure is very small and in cases of high back pressure.

Supplementary loading systems provide optimal tightness right up to set pressure and improved protection for high temperature media and high set pressures.

Change-over valves are used to connect two safety valves to a pressure system. One safety valve is in operation and the other one is on standby. The safety valve on standby can be dismounted and serviced during ongoing operation ofthesystem–theprotectionofthesystemagainstexcessivepressureremainsguaranteed.

The combination of a LESER safety valve and bursting disc combines the advantages of both safety devices.

Flanged Safety Valves

LESER safety valves have been optimized, in close cooperation with plant engineers and service specialists, sim-plifying design with fewer components for less down time, fewer spare parts and lower maintenance costs.

Integral cast support brackets for safe handling of the valves (API and heavy safety valves).

One piece spindle allows better alignment.

Guiding: Upper and lower guiding with small surface areas help reduce friction, a major cause of galling.

Long spring allows large pressure range for each spring thus drastically reducing the overall number of different springs.

Single trim for steam, gas and liquids for fewer spare valves in your stock.

Stellited or hardened metal sealing for longer product life.

LESER defines the set pressure as “initial audible discharge” (not “pop”). This avoids damage to valve seats during set pressure testing and allows for higher shut-off closer to set point.

Self-draining body avoids residue build-up and reduces corrosion.

Options

LESER´s safety valves can be customized with a great variety of options.For further information please refer to “Available options” of each Type.
