  • Can a check valve be installed vertically?

    Yes, a check valve can be installed vertically, but two critical conditions must be met: the fluid flow must be upward only, and a spring-assisted check valve must be used. Standard swing check valves without spring assistance are designed for horizontal installation only; forcing them into a vertical position will ca...

  • Which Valve Is Easier to Install in Tight Spaces: Butterfly Valve or Ball Valve?

    When space is limited, butterfly valves are easier to install than ball valves. Their wafer or lug-style body clamps directly between two pipe flanges, requiring minimal face-to-face length and no extra support structures. For large-diameter plastic piping systems in particular, the butterfly valve's slim, lightweight...

  • What Types of Plastic Valves Are Best for Corrosion-Resistant Piping Systems?

    Plastic valves are the right choice when your piping system handles corrosive fluids, requires lightweight components, or operates in environments where metal corrosion is a persistent problem. In conditions where pressure stays below 1.0 MPa and temperature below 95°C, plastic valves weigh only 30–40% of equivalent ...

Foot Valves PPN Industry knowledge

What are Foot Valves PPN?

1. Basic Principle A foot valve is a check valve installed at the pump inlet or the end of a pipeline. It opens when the liquid flows in the forward direction using a spring or gravity, and automatically closes when the liquid stops or flows backward, preventing backflow.

2. Advantages of PPN Material
PPN (Polypropylene N) is a highly transparent, low-absorption, and chemically resistant engineering plastic. It possesses excellent pressure resistance, impact resistance, and high-temperature resistance, making it suitable for applications in water treatment, chemical, and food industries where high material purity and durability are required.

3. Characteristics of Foot Valves PPN

Reliable Backflow Prevention: The valve body uses a spring-loaded self-closing structure, ensuring rapid closure regardless of changes in external pressure.

Strong Material Compatibility: PPN is virtually unaffected by acids, alkalis, salt water, and oils, extending its service life.

Lightweight Design: Compared to metal valve bodies, PPN material is lighter, facilitating handling and installation.
