Hikelok 316 Stainless Steel 3000 Psi Poppet Check Valves - CV2 Series
Hikelok CV4 check valves have been well accepted and widely used in a variety of industries for many years. A wide variety of end connectors are offered for all types of installation.NACE compliant materials and oxygen clean are also available, along with an extensive list of materials of construction.Working pressure is up to 3000 psig (206 bar),working temperature is from -10ºF to 400ºF (-23ºC to 204ºC).Every check valve is cycled six times prior to testing. Every valve is tested to ensure it seals within 5 seconds at the appropriate reseal pressure.
