  • 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...

  • 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...

  • 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 β-PPH Industry knowledge

What are Foot Valves β-PPH?

1. Basic Concept: Foot valves are self-priming valves installed at the bottom of pipelines, utilizing gravity, and are commonly used for automatic liquid discharge or backflow control. β-PPH is a β-modified homopolymer polypropylene (PPH) material with a uniform and fine crystalline structure, maintaining stability in high-temperature (up to 100℃) and highly corrosive environments.

2. Material Advantages: β-PPH combines the lightweight and chemical resistance of polypropylene with the high hardness and wear resistance resulting from β modification, making the foot valve body less prone to aging and cracking during long-term use.

3. Application Scenarios: Foot valves are widely used in pipeline systems in industries such as chemical, semiconductor, pharmaceutical, and wastewater treatment, and are especially suitable for conveying media requiring high reliability and long service life.

How durable are Foot Valves β-PPH in corrosive media such as those found in chemical, pharmaceutical, and wastewater treatment applications?

1. Chemical Media: The homopolymer structure of β-PPH makes it chemically inert in strong acid and alkali environments, resisting common corrosive solvents and resulting in a significantly longer service life than ordinary PP valve bodies.

2. Pharmaceutical Industry: Pharmaceutical production has extremely high requirements for cleanliness and material safety. The non-toxic and odorless properties of β-PPH meet GMP standards and do not produce harmful degradation products during high-temperature sterilization, ensuring long-term reliable valve operation.

3. Wastewater Treatment: Wastewater often contains corrosive salts and microorganisms. The corrosion resistance and aging resistance of β-PPH allow foot valves to maintain their sealing performance even after thousands of hours of continuous operation, greatly reducing maintenance frequency.

4. Overall Performance: In actual projects in the above three industries, the mean time between failures (MTBF) of Foot Valves β-PPH can reach more than 5 years, far exceeding the service life of traditional metal valves or ordinary plastic valves.
