Structural Characteristics and Uses

1.The operation reduces eoart:The medum pressure w producethe good acfon on the spherold to transmnt omplelely gives mhe lower beang.he spheroid relatve postion milraion.,the bohsidesvalve seat seal stress will not be even,the operation moment of force will be low.

2. Uses the spng pre-Canada load the movable metal valve seatstnucture, can be suitable the high temperalure, he high pressure as wel as each medlum pipellne

3. According to the customer request, may design can be suitable in contains medium and so on pellet, ground paste4. Widely is suitable for medum pipelnes and so on food, medicine, petroleum, chemical industy, natural gas, steel and iron,envronmental protection, Papermaking.
