Vernay Laboratories designs and manufactures precision
molded elastomeric parts. Our primary area of expertise is in
the design and manufacture of elastomeric check valves for fluid
control applications. Our standard product lines include a variety
of check valve designs both fully elastomeric and elastomer over
molded onto metal or plastic inserts. One of these product lines
is a family of poppets which can be used to make valves. Both
all rubber designs and designs with rubber bonded to metal or
plastic substrates are available.
Poppets are typically used as check valves, pressure relief valves,
or regulating valves. They can be more expensive to apply than
other all rubber valve designs but have several advantages that
make them the desired choice as check valves, pressure relief
valves and pressure regulating valves.
Typical Poppet Valve Applications
Some of the advantages of the Vernay¡¯s all rubber
and rubber tipped poppets include:
Superior sealing and leakage prevention due to the integrally
molded, permanently bonded seal and, with guided operation, the
sealing point consistently contacts the seat at the same point
each time allowing it to conform to the shape of the seat.
Low noise (as compared to all metal poppet designs)
Streamlined flow around the ball or cone shaped tip
Precise opening pressure control as a result of using a metal
spring
Factors that should be considered when selecting a poppet valve:
The environment the poppet will work in (fluid being controlled,
operating temperature, etc.)
Desired flow rate and pressure drop
Desired opening pressure
The control required (acceptable variation) of both opening pressure
and flow or pressure drop regulation
Acceptable noise generation
