DN 300 Weflo Rising Stem Gate Valve features
Weflo Rising Stem Gate Valve is UL and FM approved. Weflo Rising Stem Gate Valve is one of the valves used as regional control valve. Rising stem gate valve, which is used to separate and control installation zones , is used as a cut-off valve in installation feed lines. Rising stem gate valve does not disrupt normal flow in fully open position. The open or closed position of the valve is understood by the up and down movement of the stem. Electrical monitoring can be done by attaching a monitoring key to rising stem valves . Rising stem valves create much less hydraulic loss compared to butterfly valves.
Its application area is very wide and it can be used at many points of the fire installation except for the places where powder and gas extinguishing is applied. However, it is mostly used in front of the water tank and in pump suction and discharge lines.
Note: There is no requirement to use OS&Y Rising Stem Valve in the pump discharge line according to NFPA.DN 300 Weflo Rising Stem Gate Valve Technical Data
