Description

Delta-Elektrogas VS Pressure Relief Valve: The VS type is a pressure relief valve designed to reduce temporary pressure surges in burning appliances. The shutting-off of automatic valves or non-tightly closing of regulators can cause pressure increase; by releasing that overpressure in a relief line, VS valve enables the system to work properly again.

Relief pressure range:

50 … 150 mbar
110 … 190 mbar
150 … 450 mbar
400 … 1200 mbar

The valves are designed and manufactured according to European Directive on Pressure Equipment 2014/68/EU (certification in progress).

2011 – Elektrogas range celebrates 30 years in the market, with a product portfolio that now includes control valves, filters, gas regulators, servomotors, and combustion controllers. Today – Elettromeccanica DELTA, with its brands Elektrogas and Deltapumps, is a proud manufacturer of safety and control products for gas firing systems and fuel oil appliances, successfully installed in more than 60 countries in the world.

Features

Valve housing is made of aluminum alloy die-cast.
Equipped with adjustable spring, so that relief pressure can be precisely set up on site.
Pipe connections meet group 2.
Designed for high relief flow.
Suitable for use with air and non-aggressive gases included in the 1, 2 and 3 families (EN 437).
Special versions for aggressive gases (like biogas or COG) are free of non-ferrous metals and provided with rubber part made of FKM (J version).
Provided with pressure test points on two sides in the inlet chamber to connect manometers, pressure switches or other gas equipments.
All components are designed to withstand any mechanical, chemical and thermal condition occurring during typical service. Effective impregnation and surface treatments are used to improve mechanical sturdiness, sealing and resistance to corrosion of components.
Valves are 100% tested and fully warranted.

Applications

In a relief valve inlet pressure acts on one side of a diaphragm, while on the other side there is a spring. Diaphragm is connected to the disc: when force of inlet pressure is higher than spring force, diaphragm moves and disc opens releasing gas in relief line. After discharging pressure surge, inlet pressure gets lower and disc closes again. Relief pressure can be set operating on
the spring.
