  • 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 β-PPH Industry knowledge

What are some typical case studies of β-PPH check valves in actual projects?

1. Solar Photovoltaic Systems
Check valves made of β-PPH material allow for unidirectional flow in photovoltaic branch pipelines, preventing backflow and subsequent back pressure damage to the photovoltaic inverters.

The valve body is lightweight and corrosion-resistant, suitable for the high-temperature and ultraviolet environments of photovoltaic arrays.

Typical Project: Several distributed photovoltaic power stations in Jiangsu Province have adopted β-PPH check valves for reliable pipeline protection.

2. Semiconductor Manufacturing Processes

Semiconductor production lines have extremely high requirements for fluid purity and pressure control. The chemical resistance of β-PPH check valves effectively prevents backflow of acidic and alkaline media.

The valve body uses a metal flange connection, ensuring reliable sealing and meeting the high-pressure requirements of cleanrooms.

Typical Case Study: The cleaning fluid circulation system of a large domestic semiconductor plant uses β-PPH check valves, significantly reducing the leakage rate.

3. Chemical and Pharmaceutical Piping
In the transportation systems of chemical and pharmaceutical industries, β-PPH check valves can resist the erosion of strong acids, alkalis, and corrosive media, ensuring pipeline safety.

Its homopolymer polypropylene β-modified structure provides excellent temperature and pressure resistance.

Typical Project: β-PPH check valves supplied by Jiangsu Runhe Company for PPH pipeline systems have been put into use in several chemical enterprises.

4. Environmental Protection and Wastewater Treatment
β-PPH check valves prevent backflow in the return pipelines of wastewater treatment plants, protecting pump station equipment.

Due to the material's resistance to aging and low maintenance costs, they are suitable for environmental protection facilities operating for extended periods.

What sealing materials are typically used for β-PPH check valves?

1. Polytetrafluoroethylene (PTFE)
PTFE possesses an extremely low coefficient of friction and excellent chemical inertness, making it a commonly used sealing material for β-PPH check valve seats. It can maintain sealing performance in high-temperature (≈177℃) and strong acid/alkali environments.

2. Fluoropolymer Series (FEP, PFA, PCTFE)
In aerospace and high-end chemical fields, some valves use fluoropolymers to improve corrosion resistance and high-pressure resistance.

3. Metal elastomers (such as fluororubber FKM) For applications requiring higher elasticity, FKM offers better resilience and oil resistance.
