OLCV6
Lift Check Valves
Features
■ OTG Lift Check Valve has been designed for a wide variety of temperature extremes found in power, chemical, petrochemical, oil & gas, and laboratory applocations.
■ Pressure rating up to 6,000psi (413bar) @100°F(38°C)
■ Temperature up to 900°F(482°C)
■ SS316 stainless steel construction.
■ No spring or elastomers.
Operation
■ Forward flow lifts the poppet, opening the valve.
■ Reverse flow seats the poppet against the orifice, closeing the valve.
■ Reverse flow coefficient less than 0.1% of forward flow coefficient.
■ The lift check valve is gravity assisted poppet uses back pressure to achieve a seal and must be mounted horizontally, with bonnet nut on top.
