Elastic seat sealed plug valve provides reliable applications and offers availability and long service life for various medium, high-speed, corrosive fluid and fluid with impurity.
Features:
1.Special corrosion-resistant seat: Nickel-surfaced or stainless steel seat is firmly connected with the valve body, which can stand the wearing of solid particles, and resist to the destroying of corrosive medium and the scouring of high-speed fluid. High-interchangeability sealing parts is re-used by only changing the cock of valve.
2.Wholly rubber-coated cock: the whole cock of all diameters applies up-to-date vulcanization process, its outer surface is coated with high-performance rubber. It has ability of excellent sealing elasticity and resistance to fluid corrosion and high-speed fluid scouring.
3.Integral bow-shaped valve shaft: The valve shaft and cock are integrally cast with high transmission strength and rigidness. The bow-shaped valve shaft structure is applicable for keeping away from the passageway of fully-opened valve, and offers remarkable diversion efficiency. Its weight is less than traditional plug valve and segment valve.
4.Rectangular through passageway: The through passageway has a less fluid head loss; its rectangular section can be applied as hand-, electrically- or pneumatically- driven control valve, and enjoys very good flow regulating linearity.
