The Anka Plastic Foot Valve minimises the development of reverse flow that may cause damage to pumps and equipment. These valves restrict flow to a single direction with a spring return to close the passage. The Anka Foot Valves are an inexpensive way to ensure that a centrifugal pump is primed every time it cycles and can be installed in any orientation, as long as the direction of flow is specified. It is highly recommended that a Foot Valve Bracket is used in conjunction with the valve to avoid suction of debris into the system. The ANKA Foot Valves have a number of features and benefits, including: Suitable for: Pumping, Irrigation, Agriculture, Industry Applications Spring Loaded for Installation at any Angle Non-Corrosive, High-Quality Materials Serviceable Units Glass-Reinforced Nylon Body with 316 Stainless Steel Spring BSPT Threads Max.
