Abstract RU 2379556 C1

FIELD: engines and pumps.

SUBSTANCE: proposed valve serves to vary direction of the flow and/or to start (stop) compressed airflow in air lines of pneumatic drives depending upon mechanical, pneumatic or electric control effect. It consists of plunger casing at least one electropneumatic valve and mechanical back-up drive. Plunger built-up casing consists of metal perforated tube supporting parts fitted thereon and made from polymer thermoplastic material, said parts being tightened together by flanges with the help of nuts and studs. Casing tightness is provided for by a system of sealing elements. Electropneumatic valve of control valve incorporates reinforced locking elements of the armature.
