PPH Check Valve
The PPH (Polypropylene Homopolymer) Check Valve is a non-return valve engineered to prevent backflow in piping systems by allowing fluid to flow in only one direction. Made from high-purity, chemically resistant PPH material, this valve is ideal for conveying corrosive media in industrial and chemical processing applications. It offers excellent resistance to acids, alkalis, and salts, while maintaining dimensional stability and durability under pressure and temperature fluctuations.
PPH check valves are commonly used in systems that require reliable one-way flow control to protect pumps, filters, and equipment from back-pressure or contamination.
Key Features of PPH Check Valve
Chemical Resistant PPH Body – Suitable for aggressive chemical and corrosive environments.
Lightweight & Rigid Construction – High stiffness and long-term dimensional stability.
Prevents Reverse Flow – Ensures one-directional flow to protect downstream equipment.
Non-Metallic Internal Components – Ideal for high-purity and non-corrosive systems.
Low Cracking Pressure – Opens easily with minimal flow, ensuring efficient operation.
Vertical or Horizontal Mounting – Flexible installation in various pipeline configurations.
Low Maintenance Design – Easy to disassemble and clean with minimal downtime.
