Size: DN150 ~ DN3500 Nominal pressure: PN2. 5 ~ PN40 Applicable media: water, steam, gas, oil, etc. Medium temperature: ≤ 80℃ Valve open time: 10 ~ 90 seconds (adjustable) Quick clearance time: 1. 5 ~ 20 seconds (adjustable) Slow clearance time: 6 ~ 90 seconds (adjustable) Quick clearance angle: 70° ± 10° Slow clearance angle: 20° ± 10° Full-state minimum flow resistance coefficient: 0. 1 Optional control power supply: AC220V, DC220V, DC110V DC24V

Hydraulic Control Butterfly Valve Slow Close only back at home and abroad are more advanced pipeline control equipment installed in the main hydropower station turbine imports, imports of used turbine valve; or installed in the water, electricity, water supply and drainage pumping station pumps and other types of export to replace the check valve and gate valve. Job, the host with the valve and pipeline, in accordance with the principles of hydraulic transition process, through the electro-hydraulic control procedures for the effective setting, reliable pipeline implementation deadline, the effective elimination of pipeline water hammer and can achieve no automatic electric valve clearance, to play pipeline system to protect the security role.
