Electric slide valves
features
ZYH943 flat gate valve specifications are from DN25 to 1000mm commonly. Commonly nominal pressure is PN1.6 ~ 15.0MPa, some series of products use PN25.0 MPa and 42.0 MPa.
Using handwheel operation can be applied to DN25-600mm, bevel gear operation generally used for DN80 ~ 600mm, others such as pneumatic, hydraulic and electric (explosion-proof) drive device can be applied to any specifications of the valves.
Using a variety types of materials, can expand the scope of valve application, application of anti-sulfur materials and surface special process can make the valve used in the occasion of sulfur medium.
applicable temperature scope
normal temperature －29～+121℃；
high temperature －29～+250℃；
low temperature －40～+121℃。
advantages
It has full bore passage, equivalent to smooth pipeline, large flow capacity, small flow resistance, has the dual downstream sealing, without lubricant sealing part, sealing is good, high reliability, with fewer zero parts, design novel, which can meet the requirements of pipeline, and satisfy the process operation and maintenance of the user's request, can ensure valve long-term reliable operation.
Form
The flat gate valve with diversion hole, its flow characteristics is equal to the specification of the pipeline, equal percentage characteristic, without diverting hole flat gate valve, its middle cavity span is less than wedge gate valve, which belongs to regular cylinder, its pressure loss isbigger than that with diversion hole, the rest basic characteristics are almost the same.
Flow adjustable characteristic of the flat gate valve without diversion hole is better than ordinary flat gate valve without diverting hole.
