Key Features & Technical Specifications
- Durable Construction: Cast steel body (WCB/LCB/SS options) withstands harsh marine environments, corrosion, and high-pressure surges.
- Positive Backflow Prevention: Angle globe check design with a guided disc ensures tight sealing under varying flow conditions.
- Visual Position Indication: Rising stem clearly shows valve open/close status, simplifying maintenance and operation.
- Wide Pressure Range: Suitable for PN1.6 – PN6.4 MPa (Class 150 – Class 600 equivalent) to cover diverse system requirements.
- Flanged Connections: Standard flanges (RF/RTJ) compatible with most international piping codes (ANSI, DIN, GB).
- Low Maintenance: Self-cleaning seat design reduces debris accumulation, extending service life.
- Optional Coatings: Available with epoxy or zinc-rich primer for enhanced corrosion resistance in seawater applications.

Frequently Asked Questions
-
1. What media can this valve handle?
It is suitable for water, seawater, oil, gas, and steam within the pressure and temperature limits. For corrosive or high-viscosity media, contact us for material upgrades. -
2. Can the valve be installed vertically?
The angle globe check valve is designed for horizontal installation with the stem vertical. For vertical applications, consult our engineering team for orientation recommendations. -
3. What is the standard shutoff pressure?
The valve can hold backpressure up to its rated pressure class (PN1.6 – PN6.4 MPa). Seat leakage complies with Class VI per API 598. -
4. Do you offer cryogenic or high-temperature versions?
Yes. With appropriate materials (e.g., LCB for low temp, alloy steel for high temp), we can customize for extreme conditions. Request a quotation. -
5. How is the rising stem protected against marine corrosion?
Standard stem material is stainless steel with electroless nickel plating. Additional coatings like Xylan are available for severe environments. -
6. What certifications do you provide?
We are ISO9001 certified. Material certificates, inspection reports, and third-party testing (e.g., Bureau Veritas, DNV) can be provided at extra cost. -
7. What is the warranty period?
We offer a standard 12-month warranty from shipment date, covering manufacturing defects. Extended warranties are negotiable. -
8. Can I get a sample before bulk order?
Yes. Sample orders are accepted with a lead time of 20–25 days. Please contact us for sample cost and shipping details.
