A dispensing tap for liquids includes a body connected to the neck of a container, a dispensing head with an outlet or mouth, and a throat connecting the body to the dispensing head. A shut off valve is configured for sealing engagement with the mouth of the dispensing head, and a piston is axially guided within the dispensing head. The piston includes a periperhal seal slidably engaged with an interior surface of the dispensing head, and a valve stem coupled to the shut off valve. The piston is selectively actuable between a normally closed position an open position. A spring is captured between the piston and the dispensing head normally biasing the piston and shut off valve to the closed position. A vent is in communication with an interior of the body and the vent is opened and closed with movement of the piston and shut off valve.

An electromagnetic valve manifold includes a manifold base including passages, a pilot electromagnetic valve including a valve body mounted on a mounting surface of the manifold base, a gasket arranged between the mounting surface and the valve body, and a check valve. The valve body includes an electromagnetic valve-side pilot fluid discharge passage. The manifold base includes a base-side pilot fluid discharge passage that opens in the mounting surface and communicates with the electromagnetic valve-side pilot fluid discharge passage. The check valve is configured to prevent fluid from flowing from the base-side pilot fluid discharge passage to the electromagnetic valve-side pilot fluid discharge passage. The check valve is integrated with the gasket.

An isolation valve assembly having a valve body (22) provided with an inlet (23) and an outlet (24), fluidly connected by a fluid passageway (25), and an isolation valve (26, 27) that is operable to selectively open or close the fluid passageway. A vent is fluidly connected to the fluid passageway and a vent valve (34) is operable to open and close fluid communication between the fluid passageway and the vent. The vent valve comprises a stem (36) with a sealing member (37) and is operable between an open position, in which the sealing member is disposed such that the fluid passageway and the vent are fluidly connected and a closed position in which the valve stem extends across the fluid passageway and the sealing member seals the vent from the flow passageway.

Disclosed is a method of applying a biasing force against a piston in a valve as the piston moves along a piston stroke axis in a first direction and an opposing second direction, the piston having a first axial end that is a distal end of the piston, the method including: moving the piston along a piston stroke axis in the first direction and the opposing second direction, wherein while moving the piston along the piston stroke axis: applying a first biasing force in the second direction against the first axial end of the piston from a first spring, and applying a second biasing force in the second direction against the first spring from a second spring.

The sanitary diverter valve (70) is for use in a drying system or powder conveying system including conveying lines and a purge line of a purge arrangement. The sanitary diverter valve comprises a valve housing (71) with a number of openings (72, 73, 74) configured to be connected to respective lines of the system. The valve housing (71) is substantially cylindrical and includes a first opening (72), a second opening (73) and a third opening (74). Furthermore, the diverter valve (70) comprises a rotatable diversion member (75) provided with a flow channel (76) having a first end (76a) and a second end (76b), an open space (77) being defined between the valve housing (71) and the rotatable diversion member (75). The rotatable diversion member (75) is configured to be rotated between a first position and a second position to allow that fluid communication is selectively provided between the first opening (72) and the third opening (74) and between the first opening (72) and the second opening (73) of the valve housing (71).
