Model:Y565Y-2500LB-WC9-DN300 High temperature and high pressure globe valve opening and closing parts are plug shaped valve, sealing surface flat or cone, the valve flap along the center line of the fluid for linear motion. The movement of the stem form, there is lift rod type (the stem lift, hand wheel is not up and down), but also the lifting of the rotating bar type (hand wheel and the valve stem rotation, the nut is located in the valve body). Structure characteristics: 1 valve in the cavity with the pressure from the tight seal structure, the better the sealing performance. 2. The valve flap and valve seat sealing surface of the Stellite cobalt based alloy spray welding and become, wear-resisting, withstand high temperatures, corrosion resistance, scratch resistance, to be good at it. 3 high temperature creep design. 4 the valve stem adopts the whole forging structure, it has good corrosion resistance and scratch resi...
