The Univalve Piston Check Valve is reliably designed for high-temperature and high-pressure uses in a variety of environments.
ASME Section III
NPS 1/2 to 4
DN 15 to 100
Pressure Class Range:
1690 to 4500
PN 290 to 760
Seating Material: Metal
FEATURES & BENEFITS
Increased uptime from the use of anti-thrust rings in the body-guided disc, which eliminates misalignment and galling.
Greater process control due to the integral hard-surfaced seat, which allows positive shutoff and seat life
Enhanced service integrity through an optimum flow shape that minimizes flow direction changes and pressure drops.
Lower operating costs are enabled by a die-formed, flexible graphite gasket seated to a prescribed bonnet torque that provides a reliable seal.
