The steel ball valve is designed for hermetic separation (normally closed valve - NC) or connection (normally open valve - NO) of two pipeline sections by 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 with the help of mating flanges.
The presence of mating flanges provides quick removal of the valve without cutting out of pipelines.
