HENGSEN HVAC-DDF-Z-J
Cheap and fine/Not easy to jam/Technological innovation makes the valve body more impact resistant/Each valve body has been manually and equipment inspection for quality assurance
(PDF)DDF-Z-J series cast brass valve can adjust the flow of cold/hot water after it matched with DFQ-J series motor actuator.It is widely used in the liquid control system such as the central air-conditioning,heating, water disposal,industry processing and so on.
●Stem seal: four layer V type O nitrile rubber seals,PTFE envelope
●Stem material: stainless steel 06Cr19Ni10
●Valve core: brass or stainless steel
●The rest of the parts are brass
●Nominal pressure(PN): 1.6MPa
●Working medium: water,fluid temperature 5-95℃
●Valve leakage: less than 0.05% of KVs
◆ The valve stem downward running is the closing direction of the valve.
◆ Make sure the pipe is clean and without oxide and metal after welding before installation.
◆ It must be at the same point and free from shocks when connect the pipe and valve body. The flow direction should be same as the direction of the label.
◆ When the actuator is vertically installed on the valve,please avoid installing it under the valve to leave enough space for daily maintenance(like remove the actuator).
◆ Cut off the electricity to make sure there is no pressure in the water system when maintenance.
