1.Features Of High Performance Metal Sealed Butterfly Valve
VBJG High performance metal sealed butterfly valve adopts “Inclined oval disc radial dynamic balance sealing system” to attain the frictionless action between the gasket of the disc and the sealing face of the seat before valve closing. The pressure angle is bigger than the friction angle on the sealing face for which the extra-low open resisting force and rapid closing automatic tally sealing action are available. The valve features with advanced construction, reliable seal, long life, low cost.etc. It is an economical practical automatic control valve providing both control and cut-off functions and uses to the fluid services with large flow, low pressure drop and low seat leakage.
Features: Patent No. ZL200820238488.1
1. The optimum design of eccentric size ensures that the disc’s seal ring can be disengaged from the seat ring sealing surface immediately during the opening and closing process, which leads to no friction, no jamming and small operating torque, and high sealing performance and zero leakage are available.
2. Corrosion resistant alloy replating is used for seat to make sure high reliability and long service life.
3. The special processing technology is used for high precision and field-replaceable for seal ring.
4. Special non-metallic materials are used to make sure high temperature performance, strong self-lubricating and low friction. The dust and granular media can be effectively prevented into the space between the stem and body to avoid jamming.
5. High-strength stainless steel is used for integral stem and other parts to ensure high allowable pressure differential.
