Product Name: Z45X dark rod soft seal gate valve
Product type: Z45X-10/16
Product features
In 1, the valve cavity without the gate slot:
The traditional valve because the valve cavity having a bottom gate slot, long time use the back brake groove tend to deposit sand and other debris, causing the valve closure lax generate water leakage or unable to close. The company's production of soft sealing gate valve with the same flat bottom pipe design, valve cavity without the gate slot, without causing debris deposition, so that the fluid smooth operator.
In 2, the whole valve plate coated with rubber:
The valve plate adopts the high quality rubber as a whole coating, advanced technology allows vulcanized rubber after the valve plate can ensure the precise geometry, and firm adhesion, is not easy to fall off and good elastic memory.
3, corrosion resistance:
Valve stem, valve stem nut, sealing sleeve made of corrosion resistant material of stainless steel and copper, the valve body and the epoxy resin electrostatic spraying, no rust water and causing medium pollution, can meet the requirements of direct drinking water.
4, reliable sealing:
Using the three " O type sealing washer switch ", lightweight, reliable sealing; no disk root, usually free of maintenance, long service life of products.
In 5, with pressure change: unique design makes " O type sealing ring " can be very conveniently achieved in without water pressure change under the condition of.
6, embedded copper nut: copper nut and the valve plate are connected by embedded, so that the two are combined into one, will not loosen or fall off.
7, precision casting: body by precision casting technology, precision geometry makes the interior of the valve body without any finish can ensure the valve seal.
