TRUDESIGN Non-Return Valve (Black) - Temp Service: 65 Degree Celcius

TruDesign® 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.

Features:

• 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 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

  * 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 to excessive 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).
