Shanghai Zhibang Valve Manufacture Co., Ltd. proudly presents our High Temperature Threaded Plunger Valve for Water Jet Equipment, engineered to deliver reliable performance under extreme conditions. Rated for 350°F (177°C) and capable of handling 15 GPM (56.8 L/min) flow, this valve incorporates premium PTFE seals that ensure leak-proof operation even in hot water jetting applications. As an ISO9001 certified manufacturer since 2016, we combine precision machining with rigorous quality control to offer a durable, maintenance-friendly solution for demanding industrial environments.
This plunger valve features a threaded connection (NPT or BSPT), making it easy to install directly into existing piping systems without special adapters. The robust design minimizes pressure drop while providing excellent throttling and shut-off capabilities. Whether you are using it for surface cleaning, descaling, or hydrostatic testing, our valve ensures consistent flow control and long service life.
Key Features & Technical Specifications
- High Temperature Resistance: PTFE seals and engineered body materials withstand continuous operation at 350°F (177°C).
- Precise Flow Control: Plunger design allows accurate modulation from full open to drip-tight shut-off.
- Low Maintenance: Self-lubricating PTFE seals reduce wear and require no additional grease.
- Corrosion Resistant: Available in stainless steel or carbon steel with optional coating for harsh environments.
- Versatile Connection: Threaded ends (NPT/BSPT) in sizes from 1/4" to 1" – compatible with common water jet fittings.
- Compact & Lightweight: Space-saving design ideal for mobile or fixed water jet skids.

The plunger valve design offers distinct advantages over traditional ball or gate valves in high-temperature water jet systems. The linear motion of the plunger provides a straight-through flow path that minimizes turbulence and erosion, while the PTFE sealing ring ensures a tight seal even after thousands of cycles. This makes it an excellent choice for applications where frequent cycling and exposure to hot water are common, such as in pressure washers, industrial cleaning rigs, and process water systems.
We understand that every installation has unique requirements. That’s why we offer customization options including alternative seal materials (e.g., PEEK, graphite), extended stem lengths, and special thread configurations. Contact our engineering team to discuss your specific needs.

Frequently Asked Questions (FAQ)
-
Q: What is the maximum operating temperature for this valve?
A: The valve is rated for continuous operation at 350°F (177°C). For higher temperatures, alternative seal materials like PEEK or graphite are available upon request. -
Q: Can this valve be used with cold water as well?
A: Yes, it works perfectly with cold water, but it is specifically engineered for high-temperature environments. The PTFE seals maintain their integrity from -20°F to 350°F. -
Q: What thread types are available?
A: Standard options are NPT and BSPT. Custom threads (e.g., BSPP, metric) can be machined to order. -
Q: Is the valve suitable for continuous duty cycling?
A: Yes, the plunger mechanism is designed for frequent cycling with minimal wear. The PTFE seal provides a self-lubricating surface that extends service life. -
Q: Do you provide certifications for material traceability?
A: Yes, we can supply material certificates (MTC) and hydrostatic test reports upon request at the time of order. -
Q: What is the lead time for standard orders?
A: For standard sizes (1/4" to 1") and material, lead time is typically 15–20 working days. Custom orders may take 25–30 days. -
Q: Can I get a sample before placing a bulk order?
A: Yes, sample orders are welcome. We can provide a single valve with your required configuration for evaluation. -
Q: What payment terms do you accept?
A: We accept T/T, L/C, and Western Union. For new customers, a 30% deposit is required with the balance before shipment.
