  • 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 ...

Check Valves PPN Industry knowledge

What is Check Valves PPN?

1. Check Valves PPN is a product series of check valves that enables the flow of media in a piping system to be directed only in the forward direction, preventing backflow.

2. The valve body produces almost no leakage when closed and maintains a low pressure drop when open, meeting industrial requirements for safety and reliability.

3. "PPN" is the model designation for this series, representing a specific structure or material specification, facilitating selection under different operating conditions.
