Marine cast steel gate valves are specifically designed for use in shipbuilding and industrial applications. These valves are ideal for controlling the flow of various media, such as fuel oil, lubricating oil, water, and steam, with operating temperatures up to 120°C. They prevent backflow and ensure reliable performance in critical systems.
The valves are manufactured according to JIS standards and are available in two types: JIS 7363C 5K and JIS 7366 10K. Both types feature a flanged connection, manual actuation, and are suitable for sizes ranging from DN50 to DN400. The normal pressure is 0.49 MPa, with a sealing pressure of 0.76 MPa and an intensity pressure of 1.03 MPa.
Key components of the valve include:
- **Body and Bonnet**: Cast Steel
- **Disc and Seat**: Stainless Steel
- **Stem**: Stainless Steel
- **Packing**: Flexible Graphite
These valves are commonly used in marine and industrial piping systems where durability and reliability are essential. Their design ensures minimal leakage and long service life under demanding conditions.
**Packaging & Shipping**
All products are inspected before shipment. Standard packaging includes veneer board boxes for valves, expansion joints, and water meters, while pipes are packed in woven bags. Flanges and fittings are shipped in veneer board cases with plastic film. Custom packaging options are also available upon request.
For shipping, we offer multiple methods:
- **Express delivery** (FedEx/DHL/UPS/TNT) for samples, door-to-door.
- **Air or sea freight** for bulk orders, with airport or port delivery.
- **Customer-specified forwarders** for flexibility.
