Detailed Introduction

平板闸阀 FLAT PLATE GATEVALVE

(K)WPZ43F/943F/543F/643F、(K)DPZ43F/943F/543F/643F

The main features of plate gate valve

1,The company has introduced foreign advanced technology of flat gate valve and made significant improvement Its structure is reasonable,sealing is reliable and maintenance is convenient

2,Gate and seat are processed by special process and sprayed with cemented carbide and polytetrafluoroethylene to achieve double sealing.And can grease auxiliary seal double protection,seal more reliable, longer service life.

3,The unique triple adjustable packing structure of this valve ensures reliable sealing with bonnet and stem.Flange connection size according to JB/T79,also according to customer requirements specified standards.

4.The plate gate valve with orifice is used in the pipeline requiring ball pigging,and the plate gate valve without orifice is used in the pipeline not requiring ball pigging.

5,valve body cavity pressure rise,the valve seat can be automatically back off from too high pressure.

6,the valve drive mechanism to ensure that the valve open and close flexibly,the opening and closing torque is only1/3~1/2 of the ordinary valve.

7,pneumatic gate valve open and close quickly,with buffer mechanism,open and cose without impact,pneumatic,manual conversion structure,flexible,convenient and reliable.

8,regulating type flat gate valve is suitable for pump,station outlet and other need to adjust the medium of the pipeline,regulation and cut off the medium.

9,the valve can be widely used in natural gas,petroleum,chemical,environmental protection and other transmission pipelines,vent system and oil,gas storage device,as a device for opening and closing.

10,The company also produces flat gate valves for regulating and other special requirements.

11,electric plate gate valve generally choose yangzhou electric power repair factory or tianjin ertong electric head,also according to the needs of users with Rotork(IQ)series,Germany omar Aul(SA series)or by customers in the domestic selection of any manufacturers electric head.
