Parallel Double Gate Valve

Description

The Parallel Double Gate Valve uses two parallel discs that are spread against the body seats by a wedge mechanism at the end of closing. Because the discs move parallel to the seats, sealing faces suffer minimal friction and wear, and the valve is less prone to jamming from thermal expansion. Its cast iron construction makes it a durable, economical isolation valve for water and low-pressure steam.

Technical Specifications:

• Pressure Class: PN10 / PN16 (1.0 – 1.6 MPa)
• Size Range: DN50 – DN1200
• Applicable Medium: Water, steam, oil
• Operating Temperature: ≤ 200°C

Main Parts and Materials:

Key Product Features:

1. Double Disc Sealing: Two discs seal on both seats at the same time for reliable closure.
2. Low Seat Wear: Parallel motion avoids sliding friction until the final wedging stroke.
3. No Thermal Binding: Parallel design is less likely to stick when temperatures change.
4. Copper Seat Rings: Corrosion-resistant sealing faces extend service life.
5. Full Bore: Straight-through flow with low pressure drop.

Applications:

Ideal for Water Supply, Heating Networks, Paper & Chemical Plants, and Mining Drainage. Specifically suited for full-open / full-close service on clean media.
