UPVC Spring Check Valve
The UPVC Spring Check Valve is a precision-engineered non-return valve designed to automatically prevent reverse flow in pipelines by using a spring-loaded mechanism. Made from Unplasticized Polyvinyl Chloride (UPVC), it offers excellent resistance to corrosion, chemicals, and low-pressure environments. The integrated spring mechanism provides quick and reliable valve closure, ensuring flow protection in vertical or horizontal installations.
This valve is ideal for use in water treatment systems, chemical dosing lines, irrigation networks, and various industrial applications where clean, controlled flow is required. Its compact, lightweight design ensures easy installation, minimal maintenance, and dependable performance over time.
Key Features of UPVC Spring Check Valve
Spring-Loaded Design – Ensures quick closure to prevent reverse flow and water hammer.
High Corrosion Resistance – UPVC body and components resist acids, alkalis, and saline water.
Non-Metallic Construction – Ideal for chemical and non-metallic piping systems.
Low Cracking Pressure – Opens easily with minimal upstream pressure.
Compact & Lightweight – Easy to install and handle, especially in overhead or space-limited areas.
Vertical or Horizontal Mounting – Versatile installation for multiple system layouts.
Maintenance-Friendly – Simple access to internal components for inspection or replacement.
