SINGLE-PLATE GATE VALVE
Being part of the proven KÜHME shut-off valves, the gate valve type PSA-DELI-SAL is used in gas measuring and gas distribution plants, as well as in gas and oil pipelines, where safe shut-off of the gases is required. The gate valve is directly operated by a non rising hand wheel, while at sizes larger than DN 200 the gate valve comes with an additional bevel gear box and set standards in regard with enviromental friendliness and reliability.
DN 50 TO DN 500
PN 40 / 100 (Cl 300 / 600)
– 10°C bis + 80°C
- Low actuating torques+
- No spindle movement outside the gate valve
- Safety due to absolute tightness
- Robust design
- Metallic sealing system for long lifetime
- Flow-through in either direction
The open/close service of the single-plate gate valve is used for shutting-off of pipelines. The coplanar shut-off gate flap attached to the spindle moves vertically between two seat rings in vertical direction. On the side showing towards the shut-off flap, the seat rings are each equipped with a sealing ring which is pressed onto the shut-off gate flap by the medium pressure and by springs on the opposite side, thus forming a high-quality sealing system.
