Shanghai Zhibang Valve Manufacture Co., Ltd., an ISO9001-certified manufacturer since 2016, proudly presents our Stainless Steel Plunger Valve for High Pressure Food Processing, Dairy, Beverage, and Brewery. With an annual export value of US$1 million to US$1.5 million and a global market reach spanning North America, Europe, Asia, and beyond, our plunger valves are engineered to deliver reliable performance in demanding hygienic applications. The valve’s robust stainless steel construction and precision plunger design ensure leak-free operation under high pressure, making it an ideal choice for controlling flow in food processing lines, dairy pasteurizers, beverage filling systems, and brewery processes.
Our plunger valve is crafted from high-grade stainless steel (SS304 or SS316L) with a polished surface finish of Ra ≤ 0.8μm, meeting strict sanitary standards. The valve features a smooth, crevice-free interior that prevents product accumulation and facilitates easy cleaning (CIP/SIP compatible). Available in sizes from DN25 to DN100 and with multiple connection options (clamp, threaded, or flanged), it can be seamlessly integrated into existing piping systems. The plunger mechanism provides precise throttling and shut-off control, with a pressure rating up to 10 bar, ensuring consistent performance even in high-pressure applications.
Key Features & Advantages
- Sanitary Design: Full stainless steel construction with no dead zones, suitable for food-grade and pharmaceutical environments.
- High Pressure Capability: Designed for operating pressures up to 10 bar, ideal for process lines requiring safe and reliable shut-off.
- Versatile Connection: Available in clamp, threaded, and flanged ends to match your system requirements.
- Easy Maintenance: The plunger can be replaced without removing the valve body, reducing downtime.
- Seal Options: Choose from EPDM, PTFE, or silicone seals (FKM also available) for compatibility with different media and temperatures.
- Customizable Actuation: Manual handwheel, pneumatic cylinder, or electric actuator options to suit automation needs.
- Long Service Life: Hardened plunger and seat surfaces resist wear, ensuring thousands of cycles without leakage.

The plunger valve’s design incorporates a self-cleaning action: the plunger moves through the sealing area, wiping away any residual media, which reduces the risk of contamination. This feature is particularly beneficial in dairy and beverage applications where product purity is paramount. Additionally, the valve can be fully disassembled for inspection and cleaning, complying with EHEDG and 3-A sanitary standards (upon request).
For customers in the brewery industry, the valve’s ability to handle carbonated liquids and its resistance to corrosion from cleaning agents make it a reliable choice for beer production lines. In food processing, it can be used for viscous products, syrups, and sauces without clogging. The high-pressure capability ensures safe operation in pasteurization and homogenization processes.

A: The standard design pressure rating is 10 bar. For higher pressure requirements, custom solutions are available upon request. -
Q: Can this valve be used in CIP (Clean-in-Place) systems?
A: Yes, the valve’s smooth internal surface and crevice-free design make it fully compatible with CIP and SIP processes. The seal material can be selected to withstand cleaning chemicals. -
Q: What seal materials are available for dairy applications?
A: For dairy applications, we recommend EPDM seals due to their excellent resistance to hot water and steam. PTFE is also suitable for higher temperature resistance. Other options like silicone or FKM can be provided for specific media. -
Q: Is the valve suitable for use with carbonated beverages?
A: Absolutely. The valve’s robust construction and tight sealing prevent gas leakage, making it ideal for carbonated beverage lines. The material does not react with CO2. -
Q: What connection types are available?
A: We offer clamp (tri-clamp), threaded (BSP, NPT), and flanged connections (DIN, ANSI). Custom connections can be manufactured upon request. -
Q: Do you provide certificates of material and pressure testing?
A: Yes, we provide material certificates (3.1) and hydrostatic test certificates with each shipment. Additional certifications can be provided at extra cost. -
Q: What is the minimum order quantity (MOQ)?
A: Our standard MOQ is 5 pieces per size, but we can accommodate smaller orders for sample or trial purposes. Contact us for details. -
Q: How long does the valve last in continuous operation?
