Base plate valve improvements

the cover plate-shaped instead of convex.
A "hiding place" for the valve plate design, the valve plate opens fully retracted into the cavity of the valve cover. First, the open channel to increase the flow area, the second is to avoid the gas entrained dust erosion. The original design of the valve plate open is hanging in the valve body of the gas channel occupies the effective diameter of about 20%. Increase the gas flow resistance, impact on the efficiency of the gas, improved diameter at 100% utilization.angle seat valve
Improved sealing form:
Bevel seal has been used for many years, concluded learned that the seal on the easy adhesion foreign body, often fouling substances appear in the local area, and easy to flake off affect the sealing performance. Into line encrypted form narrow sealing surface sealing surface by the force increases.
Difficult to produce foreign body adhesion on, off the impact from grinding, self-healing effect. Time after sealing surface automatically widened, maintain long-term sealing effect.pneumatic accessory
