Tru-Design Non Return Valves

Tru-Design Non Return Valves are designed for marine, farming, horticulture and mining industries. Made from UV stabilised glass reinforced Nylon, these composite material fittings are designed for the harsh marine and agricultural environments. They can be used in Line to prevent water backflow or siphoning and have a very low cracking pressure.

• Manufactured from a high strength, UV stabilised 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 flowrate
• 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

• Choosing the right size valve for your application will reduce risks of wear, vibrations and Noise. It is better to avoid using a valve either too small (leads toexcessive velocity and wear) or too large (leads to vibration, Noise and possibly premature wear of a non-return valve plunger that is never fully open).
• Ensure the non return valve is enstalled with water flowing in the same direction as the white arrow
• Use 2 hose clamps on each end, ensuring not to over tighten
• Recommend use of a filter or strainer in flow path, feed side of the non return valve. Disconnect pipes & check for blockages every 6 months.
• For clear water use only
