Shanghai Zhibang Valve Manufacture Co., Ltd. is a professional manufacturer specializing in high-pressure fluid control solutions since 2016. Our Low Leakage Plunger Valve – 316L SS, 30,000 psi, 0.05% Leakage is engineered specifically for demanding laboratory high-pressure fluid test applications. With a robust design and precision manufacturing, this valve delivers exceptional sealing performance, minimal internal leakage, and long service life under extreme conditions. Backed by our ISO9001-certified quality management system, every valve is rigorously tested to ensure reliability and accuracy in critical fluid control tasks.
Key Features & Technical Specifications
- Material Excellence: Constructed from high-grade 316L stainless steel, offering superior corrosion resistance against a wide range of chemicals and fluids commonly used in laboratories.
- Ultra-High Pressure Capability: Rated for 30,000 psi (2,068 bar) working pressure, suitable for high-pressure chromatography, hydraulic testing, and supercritical fluid applications.
- Extremely Low Leakage: Factory-tested leakage rate of ≤0.05% of full flow, ensuring precise control and minimal fluid loss, critical for accurate test results.
- Plunger Design: The plunger-type sealing mechanism provides linear flow control, low torque operation, and excellent throttling ability, reducing wear and extending valve life.
- Customizable Connections: Available with standard NPT or coned-and-threaded ports; other connection types can be customized upon request.
- Optional Seal Materials: Standard seals are PTFE-based; PEEK or other high-performance polymers are available for higher temperature or chemical resistance needs.
- Compact & Lightweight: Designed for easy integration into laboratory test benches, with a compact footprint without compromising performance.

Frequently Asked Questions (FAQ)
- What fluids can this valve handle? – The 316L SS body makes it compatible with most non-corrosive and mildly corrosive fluids, including water, oils, hydraulic fluids, and many chemical solvents. For highly aggressive fluids, please consult our technical team for seal material recommendations.
- What is the maximum operating temperature? – Standard configuration is rated from -20°C to +100°C. With optional PEEK seals, the temperature range can be extended up to 260°C.
- Are custom connection sizes available? – Yes, we offer custom port sizes and thread types (e.g., BSP, metric, or special coned-and-threaded connections) upon request. Minimum order quantities may apply.
- Is this valve suitable for gas or liquid service? – It is designed for both liquid and gas high-pressure applications. However, for gas service, additional cleanliness and internal leakage testing may be required; please specify your application.
- What certifications does the valve have? – Our manufacturing facility is ISO9001:2015 certified. Individual valve test certificates (with actual leakage and pressure test data) can be provided upon request.
- What is the typical lead time? – Standard models (1/4" NPT, PTFE seals) are usually shipped within 2–3 weeks after order confirmation. Customized orders may take 4–6 weeks depending on complexity.
- How do I maintain the valve? – For infrequent use, periodic cycling and cleaning of the plunger stem is recommended. For high-frequency operation, inspect seals every 6 months and replace as needed. Detailed maintenance instructions are included with each valve.
- Can I get a sample for testing? – Yes, we offer sample orders for evaluation prior to bulk purchase. Please contact our sales team to discuss terms.
