Single-plate gate valve
TYPE PSA-DELI SIL

Being part of the proven KÜHME shut-off valves for the municipal gas supply, the gate valve type PSA-DELI is used in any application where safe shut-off of the gases is required in accordance with DVGW G260 I and II. The single-plate gate valve, which is actuated by a rigid- or telescoping mounting set, sets new standards in regards with service life and reliability.

Application areas

Shut-off gate valve in municipal, underground gas supply systems for natural gas G260, according to DVGW I/II

Nominal size: DN 50 to DN 300
Nominal pressure: PN 6 / 16
Installation length: according to DIN 3202, part 2
Operating temperature: - 10°C to + 70°C

Advantages
  • Low actuating torques
  • With internal spindle thread
  • Safety due to absolute tightness
  • Robust design
  • Flow-through in either direction
  • piggable
Function
The single-plate gate valve for open/close serivice is actuated by a telescope or rigid lever set mounted to the square-cut spindle. It is key-operated from above the street cap

Technical features
