Detailed Product Advantages
The High Pressure Plunger Valve is engineered for applications where absolute cleanliness and high-pressure control are critical. The 316 stainless steel material provides superior corrosion resistance, making it suitable for aggressive media such as CIP solutions, pharmaceutical ingredients, and high-purity water. The pneumatic actuator enables remote and automated operation, reducing manual intervention and improving process efficiency.
Compared to traditional ball or diaphragm valves, the plunger design offers a straighter flow path, minimal pressure drop, and excellent throttling capability. The linear motion of the plunger ensures precise regulation of flow, even at high differential pressures. The valve is also designed for easy disassembly and cleaning, complying with sanitary standards like 3A and EHEDG (upon request).
We offer a range of actuator options: double-acting for fail-in-place, or spring-return for fail-safe (open or closed). Position feedback (limit switches, solenoid valves) can be integrated for remote monitoring. The valve is also compatible with various control systems (PLC, DCS).

Frequently Asked Questions (FAQ)
-
Q: What is the maximum working pressure of this valve?
A: The valve is rated for 200 bar (2900 psi) at ambient temperature. For higher temperatures, please consult our technical team for derating factors. -
Q: Is the valve suitable for food-grade applications?
A: Yes, the 316 stainless steel body and sanitary finish (Ra ≤ 0.8 μm) make it suitable for food, beverage, and dairy processes. The valve can be supplied with FDA-approved seals upon request. -
Q: Can the pneumatic actuator be used in hazardous areas?
A: Standard actuators are not explosion-proof. However, we can provide intrinsically safe solenoid valves or ATEX-certified actuators for hazardous environments (available upon request). -
Q: What types of connections are available?
A: We offer threaded (BSP, NPT), tri-clamp (sanitary), and flanged (ANSI, DIN) connections. Customized connections are also possible. -
Q: How do I select the correct actuator size?
A: Actuator sizing depends on the required torque, supply air pressure, and fail-safe requirements. Our sales team can help you choose the appropriate actuator based on your operating conditions. -
Q: What is the delivery time for standard valves?
A: For standard sizes with common seals, delivery is typically 15–25 working days after order confirmation. Customized configurations may require longer lead times. -
Q: Do you provide warranty and technical support?
A: Yes, we offer a 12-month warranty against manufacturing defects. Our technical support team is available via email, phone, or video call to assist with installation, troubleshooting, and maintenance. -
Q: Can the valve be used for steam applications?
A: The standard version is not recommended for high-temperature steam. For steam service, we recommend upgrading to high-temperature seals and a higher temperature rating. Please contact us for specific recommendations.
