- MSGV (Metal Seated Gate Valves) are designed with a non-rising spindle and feature a precision-machined metal wedge gate that provides a durable metal-to-metal seal.
- These valves are ideal for clean water applications where higher wear resistance is needed.
- The robust design ensures reliable shut-off and long service life.
- Suitable for operating temperatures from 0°C to 80°C.
Characteristics
-
MSGV valves close clockwise (CTC) as standard. Clockwise to open (CTO) is available on request.
-
Manufacturers coat all internal and external cast surfaces with fusion-bonded epoxy powder, minimum 250 μm DFT.
-
The epoxy coating is WRAS-listed for potable water and complies with BS 6920 water quality standards.
-
Coating colours: blue (RAL 5005) for potable water and red (RAL 3001) for fire hydrant systems.
-
Standard valves use manual operators: cap top, hand wheel, or bevel gear, depending on size. Actuated options include electric, pneumatic, or hydraulic drives.
An MSGV (Metal Seated Gate Valve) suits potable water systems that demand durability, temperature resistance, or fire safety. Unlike resilient seated valves with rubber or elastomer seals, an MSGV relies on precision-machined metal-to-metal seating. This design resists abrasion, sediment, and suspended solids. It withstands higher temperatures, making it ideal for hot water or industrial use. MSGVs also meet fire-safe requirements, maintaining integrity when elastomers fail. Many utilities choose MSGVs for proven reliability, legacy specifications, and strength under frequent use. Though resilient seated valves dominate potable water service, MSGVs remain a robust, long-lasting choice for demanding conditions.
