Single-plate gate valve
TYPE PSA-DELI GAL

Being part of the proven KÜHME shut-off valves, the gate valves type PSA-DELI GAL 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 or ba means of an electrical multiturn actuator and sets standards in regard with environmental friendliness and reliability.

Application areas
  • Shut-off of gas measuring and gas regulating units, as well as gas and oil pipelines
Nominal size: DN 50 to DN 400
Nominal pressure: PN 10 / 16 or PN 25
Installation length: According to EN 558 part 1
Operating temperature: - 10°C to + 70°C

Advantages
  • Low actuating torques
  • With exterior spindle thread
  • Safety due to absolute tightness
  • Robust design
  • Flow-through in either direction
  • piggable
Function
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. On the side showing towards the shut-off gate 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.

Technical features
Valve body: Spheroidal graphite iron GGG with bolted cover, no oil filling
Sealing system: Floating support of the spring-loaded sealing system consisting of the shut-off gate flap and seat rings with one soft sealing ring each
Sealing of Spindle: With sealing rings and O-rings
Actuator type:
  • Rising spindle with non-rising hand wheel

  • Rising spindle with electrical multiturn actuator

Process connection: Flange connection in acc. with EN 1092-1
Special features:
  • DIN DVGW tested up to PN 16
  • Nickel-plated shut-off gate flap
  • The sealing system prevents dirt penetration in during the entire stroke movement when the gate flap is moving
  • Automatic overload pressure relief between housing and pipeline
  • Nearly maintenance-free
  • In opend position, gate flap and seat rings form a guiding pipe
  • Opening passage piggable
