Valve dahna specification leh model te hian design mamawh a phuhruk lo.
Entirnan, valve-a nominal pressure chu system test pressure aiin a tlem zawk a; pipe diameter 50mm aia tlem emaw, a tlukpui emaw a nih chuan feed water branch pipe atana gate valve; tui lum tihlumna atana dry leh risers te; leh fire pump suction pipe hian butterfly valve a hmang bawk.
A rah chhuah: valve hawn leh khar dan pangngai a nghawng a, resistance, pressure leh hnathawh dangte a siamrem bawk. System hnathawh tir pawh nise, valve chhiatna chu siamthat a ngai a ni.
Thiltih dan: Valve hrang hrangte hman dan tur hriat chian la, design mamawh angin valve specification leh model te thlang rawh. Valve-a nominal pressure hian system test pressure-a thil mamawh a tlin tur a ni. Construction code angin: pipe diameter 50mm aia tlem emaw, a tlukpui emaw a nih chuan stop valve hman tur a ni; pipe diameter 50mm aia tam a nih chuan gate valve hman tur a ni. Tui lum vawt vawt, vertical control valve hman tur a ni gate valve, fire water pump suction pipe hman loh tur a nibutterfly valve a ni.
Chu bakah, Tianjin Tanggu Water Seal Valve Co., Ltd. hi technology lama hmasawn tak elastic seat valve thlawptu enterprise te a ni a, a thil siamte chu elastic seat wafer butterfly valve, lug butterfly valve,double flange concentric butterfly valve a awm bawk, double flange eccentric hnim hring valve, balance valve,wafer dual plate check valve a ni, Y-Strainer leh a dangte. Tianjin Tanggu Water Seal Valve Co., Ltd. ah hian industry standard sang ber nena inmil first-class product kan pe thei hi kan chhuang hle. Valve leh fitting hrang hrang kan neih avangin i tui system atana solution tha ber kan pe thei ang tih i ring thei ang. Kan thil siam chungchang leh kan tanpui theih dan tur hriat duh chuan vawiin hian min rawn biak theih reng e.
