Steel Ball Valve for Sealing and Connection - AТЭК.491284.540

The steel ball valve is designed for hermetic separation (normally closed valve - NC) or connection (normally open valve - NO) of two sections of the pipeline on commands of control and protection systems. The valve is controlled by electric actuator or manual actuator installed on the valve. The tightness of the valve is class A of GOST 9544.

The valve is hermetically sealed in relation to the external environment. Connection to pipelines is welded. Welding is carried out by means of adapters on mating flanges.

The presence of mating flanges with adapters, which are elements of the design, provides a quick removal of the valve without cutting from the pipelines.
