Suitable for draining gas to ambient atmosphere with pressure increase in the gas pipeline. To be installed at gas control points and gas control equipment.

Nominal valve size 50 mm.

Three valve options differ in actuation pressures:

1. SDV-50L is a low actuation pressure valve (actuation pressure may be adjusted from 0.02 to 0.05 bar)
2. SDV-50M (medium actuation pressure valve with range of pressure adjustment 0.2 to 0.5 bar)
3. SDV-50H (high actuation pressure valve with actuation pressures 0.5 to 1.25 bar)..

Fluid temperature: -15 to +50^оС.

Body available in several grades of cast iron. Connection with pipeline: female threaded (2").

To be used in regions with temperate climate.

Features and advantages:

• The full cycle of test guarantees in any case leak-proof function of the valves.
• Valves need no servicing (designed for long-term function)..
• When pressure rises, sealing disk moves and gas is dumped into atmosphere. When pressure lowers to nominal spring locks the valve again.
