wafer knife gate valve

Wafer type knife gate valve is used for sewage medium,Tianjin Tanggu Jinbin Valve have own R & D department for manufacture wafer knife gate valve,flanged knife gate valve,lug wafer knife gate valve ect. The wafer knife gate valve is structure is simple， have rising stem and non-rising stem type. Wafer knife gate valve usually used for low pressure working conditions,from DN50-DN250 not more than 10 bar, from DN300-DN450 not more than 6bar, from DN500-DN600 not more than 4 bar. Wafer end knife gate valve working temperature from -10-80℃

Non-rising stem knife gate valve have a stem nut on the disc,when turn the stem by hand,the disc will go up and down with the stem nut,this design used where the installation space is limited. We have some large diameter knife sluice gate valve body in stocked,so we can provide short lead time for our customers. All the flange knife gate valve will tested one by one before shipping,test according to API598 GB/T13927 ext. Body test 1.5*PN,seal test 1.1*PN, if the knife gate valve is bi-directional, then we will test two side of seal.

knife gate valve used lost foam casting technology，one step molding,low cost and reliable casting quality. Jinbinvalve apply float retaining ring for cast steel knife gate valve seal, which design ensured bi-directional of the valve. The roller shaped stem ensures that the valve can be operated easily even under the maximum pressure. knife gate valve can be installed in the middle of the pipe or at the end of the pipe. The structure is firm and can be used without reducing the pressure level.

1. It adopts the wafer structure, small volume and light weight. 2. The fully open channel can prevent the medium from depositing in the valve. 3. The newly developed U-ring can ensure the good sealing performance of the valve.
