Abstract: An electrofusion saddle comprising: a thermoplastic body comprising a flange and optionally a spigot which erects from said flange; and a resistance heating coil including multiple windings, wherein said resistance heating coil is partially embedded in said flange and is partially protruding from said flange, wherein the protrusion is of at least 25% of an average external diameter of said multiple windings.

Abstract: A valve comprising a housing defining a control space with an outlet port for fluid egress from the space and at least one inlet port for fluid ingress into the space control member is displaceable between an open state in which the outlet port is open and a closed state in which the outlet port is closed. The at least one inlet port of the at least one inlet port is formed at a wall portion of the housing at an upper wall portion, and a fluid draining port is formed at or adjacent a bottom end of the housing for draining fluid from the control space. The fluid draining port serves for preventing fluid ingress into the control space.

Abstract: A valve (30) fitted within a fluid tank, the valve comprising a housing fitted with one or more fluid inlet ports, and an outlet port. The housing accommodates a float-type valve member (32) axially displaceable within the housing responsive to fluid level within the tank, between an open position in which the outlet port (58) is open, and a closed position in which the outlet port is sealingly closed. The housing is integrally formed with a nozzle member (60) being in flow communication with the outlet port and having a main portion with an outlet thereof extending within the tank.

Abstract: A valve (10) for a fluid tank, comprising a housing formed with one or more inlet (28) and outlet (20) ports, side walls and a seating wall (14) portion supporting a float-type valve member. The valve member is axially displaceable within the housing responsive to fluid level within the tank, between an uppermost position and a lowermost position, and has a top and a bottom end and a bearing portion facing the seating wall portion of the housing. Either one or both of the seating wall portion of the housing and the bearing portion of the valve member, are fitted with one or more dampening members (46) for diminishing impacting noise of the valve member encountering the housing upon displacement into the lowermost position.

Abstract: A valve comprising a housing defining a control space with an outlet port for fluid egress from the space and at least one inlet port for fluid ingress into the space control member is displaceable between an open state in which the outlet port is open and a closed state in which the outlet port is closed. The at least one inlet port of the at least one inlet port is formed at a wall portion of the housing at an upper wall portion, and a liquid draining port is formed at or adjacent a bottom end of the housing for draining liquid from the space. The liquid draining port serves for preventing liquid ingress into the control space.

Abstract: An over filling and roll over valve includes a housing, in which a valve assembly is located. The valve assembly includes a first stage member and a second stage member, being coaxially and relatively displaceable within the housing. The first stage member has a slit-like aperture at a bottom and an outlet aperture at the top. The inlet and the outlet apertures are in flow communication. The second stage member is a float provided with a flexible membrane strip for closing the slit-like aperture of the first stage member. The valve assembly is provided with at least one anchoring member extending between the first stage member and the second stage member and permitting a limited freedom of relative movement therebetween in such a manner that displacement of the second stage member into its second position entails positive displacement of the first stage member into its second position.
