High Quality Landing Valve for Fire Hose Hydrant (SNW65)This kind of landing valve has functions of reducing and stabilizing water pressure. It is applied in the high-rise building extinguishing system and can control the pressure and flow of water efficiently. The hydrant will adjust the pressure inside to keep the pressure stable even though the pressure of system will range.Working Principle:The piston will overcome spring force when pressure at inlet increased. The opening degree of the choke will be decreased because of the covering of piston bush, which lead to pressure at inlet increases. On the contrary, the piston will move down when pressure at inlet decreased. The opening degree of the choke will increase then the pressure at the inlet drops. For the shape of the choke is accurately designed that it can make the pressure at outlet stable.Technical parameters:   Notes: we make available customized designs for our clientsPackaging & ShippingCompany Information  With a history of more than 20 years, Shenzhen Winan Industrial Development Co.
