TruDesign Non-Return Valves are used in-line to prevent water backflow or siphoning. They are full flow with low cracking (opening) pressures. Features: Manufactured from a UV stabilized glass-reinforced Nylon composite. High strength and lightweight. Can be used in direct sunlight High impact and tensile strength - “Water hammer safe” and insensitive to pressure shocks in the pipeline Stainless spring - No corrosion issues or risk of internal valve staying open Low cracking pressure - Minimal pressure required to open the valve with minimal restriction on flow-rate In-line fitting - Minimal installation room needed and no other fittings required Printed white arrow (opposite logo side) - Quick and easy identification of water flow direction. Available in various sizes: 830876-9771 - ¾” 830876-9770 - 1” 830876-0771 - 1 1/8” 830876-9769 - 1 ¼” 830876-9768 - 1 ½” 830876-9766 - 2”
