knife gate valve

The air sealed knife gate valve is a fully closed pneumatic flat knife gate valve. The double acting straight stroke cylinder is used to directly drive the gate plate translation to realize the valve opening and closing. When the gate moves in the middle chamber, it is supported by the two-way valve seat when it moves towards the opening direction in the closed state; after a certain travel of translation, both radial sides of the gate are supported by the guide grooves of the valve body The heavy duty knife gate valve is designed with lubricating joint, the valve seal is damaged and the inner cavity is blocked. The valve body is easy to replace, seal or clean, and the pipeline under the valve is easy to disassemble and disassemble.

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℃

Bonneted flange knife gate valve is suitable for water, sewage, watertreatment in dustry, the main feature is a floating self-sealing, biaxial compression enabling bi-direction alsealing, high tightness.

The large size knife gate valve have small torque, di-directional sealing, no requirement for medium flow direction. The big size knife gate valve valve disc is polished on both sides to reduce the operating torque,reduce parts and components as much as possible, with low failure rate. Jinbinvalve can provide a variety of surface treatments and coatings for different applications and operating conditions to improve their different performance. Knife gate valve DN1800 can use different actuator,and different brand.

Material:cast iron body and bonnet Direction of flow:bi-directional Leakage rate:0 leakage

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.

This series standard, lug type wafer knife gate vale are suitable for the sewage treatment, the chemical industry, the manufacture paper pulp industry and the mining industry ,coal washingndustry, to circulates the medium for pipeline in and so on liquid suspending iquidze plays cuts off and clears the role.

Knife gate valve with bare stem suitable for pneumatic, electric and hydraulic actuators, customized according to customer requirements，customers can specify different brands of actuators. Bare stem knife gate valve has the advantages of small torque, short face to face dimensions and simple operation.According to different actuators, equipped with corresponding control panel or connected with PLC board, can carry out local control and remote control. The welded body bare stem knife gate valve can make large diameter , from DN200-DN1800, and from design to manufature, we have QC check every step quality, to make sure the final finish bare shaft knife gate valve have perfect performance,finally make the customer satisfied.
