Abstract: A gas pressure relief valve assembly with a normally closed check valve received in a main body. An actuator pin slidably received in a guide body threadably carried by the main body may be advanced to open the check valve and retracted to permit the check valve to close. A knob connected to the actuator pin and threadably carried by the guide body may be manually rotated in opposite directions to advance and retract the actuator pin. Rotary loosening of the threaded knob and/or loosening of the threaded guide body will retract the actuator pin and prevent opening of the check valve.

The segments are connected by one or a plurality of hinges, respectively, along the length extension of the tubular support body. The hinges are arranged in the folds of the folded bellows of the casing.

Abstract: A waterproof cover includes an operation unit for pressing a manual button of a solenoid valve main body. The operation unit includes a flexible cap, a pin guide interposed between the cap and the solenoid valve main body, and an operation pin that is inserted in guide hole of the pin guide so as to be displaced freely. The cap includes a flexible pressing portion for a pressing operation. One end of the operation pin is in contact with or close to the pressing portion, and the other end of the operation pin is in contact with the manual button.

Abstract: A spring-loaded ball valve includes a spring, a first pin, a second pin, and a handle. The spring is configured to apply pressure to the first pin and second pin when the ball valve is in both the fully open and fully closed positions. The spring applies maximum torque when the ball valve is in the fully open or fully closed position to ensure the valve remains in the fully open or fully closed position.

Abstract: An expandable pipe seal includes a sleeve that is expandable from a first, compact configuration to a second, expanded configuration having a larger outer diameter than the first configuration. The sleeve may be formed from sheet material that is rolled into a cylindrical shape such that a first longitudinal edge of the sheet overlaps a second longitudinal edge of the sheet in a circumferential direction. The sleeve is provided with first and second locking structures that cooperate to facilitate expansion of the sleeve from the first configuration to the second configuration and, thereafter, maintain the sleeve in the expanded configuration. The pipe seal includes sealing structure disposed on an outer surface of the sleeve, and which is compressed against the inner wall of a pipe to be repaired in the second configuration of the sleeve.

Abstract: The present disclosure relates to valve lockout systems, including valve lockout systems for use with an actuator and butterfly valves.
