Abstract: A protective cap for a plumbing fitting is disclosed. The plumbing fitting has a body having a cavity with a flow path extending therethrough. The protective cap comprises a sealing surface. In a first mode the sealing surface is configured to engage with the body to seal the cavity. The protective cap further comprises a receptacle for receiving an actuator. In a second mode the protective cap engages with the actuator of a mechanism fitting within the cavity such that the protective cap forms a handle for the actuator.

Abstract: A pressure independent control valve (PICV) is disclosed. The PICV has a body having a flow path extending therethrough and a cavity within the flow path to releasably receive a mechanism via an aperture. The PICV also has a cap comprising the mechanism. The cap is configured to move between a locked position where the cap is retained on the body and an unlocked position where the cap is releasable from the body. The cap is retained in the locked position by one or more bayonet fixings.

Abstract: A seal for a plumbing fitting includes two or more respective apertured sealing portions. Each apertured sealing portion independently includes one or more edge portions enclosing an aperture therebetween. The apertured portions are integrally formed.

Abstract: A plumbing fitting with a body having a flow path extending therethrough, and a receptacle disposed in the body is disclosed. The receptacle is arranged to releasably receive a mechanism is movable between a first operational position in which the flow path extends through the receptacle and the mechanism, and a second position in which the flow path bypasses the mechanism. In the second position, the mechanism can be released from the receptacle while a fluid flows through the flow path.

Abstract: A locking mechanism for a valve handle has a slider arranged to slide back and forth in a slot in the valve handle, between a lock position, in which the slider engages with a stop on the valve body and an unlock position, in which the slider does not engage with a stop. The slider is formed in two parts, which are inserted from opposite sides of the slot and snap fit together. The slider has indicia to indicate whether the slider is in the lock or unlock position, and the slider is arranged so as to cover the fastener which attaches the valve handle to the valve body.
