Valve seats and guards are machined from bar
stock or forgings with all gas passages drilled or milled smooth
to assure minimum friction of the gas flowing
through the valve. After machining, metallic valve components
are heat treated to attain optimum physical properties and maximum
resistance to abrasion and wear. The seat area is ground
flat and lapped on automatic machines for perfect sealing.
Metallic valve rings, discs and plates are also fully machined.
These components are heat treated, flattened, machined to close
OD and ID tolerances, ground and lapped to the desired thickness
and flatness. Sealing components for other types of valves including
channels and leaf springs and strips are manufactured with equal
precision and standard of quality. All components are de burred
and their corners are rounded to prevent gouging of seat or guard
or channels.
Compression springs are available in round as
well as rectangular cross-Section for optimum performance. Springs
caps or buttons also, may be furnished in metallic or
non-metallic materials.
All our valve components are offered in a wide range
of performance-proven materials to meet the specific need of the
application.
A full range of replacement components including Rings, Ported
Discs, Springs, Spring Buttons, Guides, Dampening Discs, Lift
Washers, Channels and Springs, Wear Stripes, Guide Holder, Strips
are available in the wide range of materials for all types of
valves for low pressure as well as high
pressure application up to 400KG/CM2.
