NEW REGULATORY REQUIREMENTS FOR SELECTOR VALVES OF GAS FIRE EXTINGUISHING SYSTEMS

Abstract. Selector valves are one of the main elements of centralized automatic gas fire extinguishing systems. They carry out the passage of a gas extinguishing agent in the supply directions to one of several objects of protection.

The centralized storage and selective supply of fire extinguishing gas to one of several objects of protection lead to more economical use of gas that reduces the material costs for fire extinguishing system.

Currently, the Russian industry has mastered the serial production of selector valves for various working pressures.

The draft interstate standard was developed on the basis of existing regulatory documents and contains new requirements and test methods for selector valves.

The draft interstate standard contains the term “working pressure”, which is consistent with the similar term from ISO  16003:2008, in which the widely used foreign term “maximum working pressure” is not used.

In order to comply with ISO 16003:2008, the manual starting force of the selector valve is increased from 150 N to 180 N when switching on with the hand.

The minimum duration of the electric starting impulse is limited to 2 seconds, and the maximum value is not normalized. There are introduced requirements for monitoring methods for closed and open position of the valve locking body in service, and for quickly manual closing the valve after activation.

It will improve the technical characteristics to the level of advanced mass-produced products. When developing the draft standard, the main provisions of international and European standards in this area are taken into account.

Keywords: selector valve, gas fire extinguishing agent, automatic fire extinguishing system, technical requirements, test methods
