Argus Inline Check Valves are designed to handle the toughest service conditions in oil and gas production. Our inline ball check valves are engineered and manufactured to deliver years of trouble-free service providing dependable one-way flow control where reliability is critical.
Inline ball check valves are a critical component in any flow system designed to provide effective positive shutoff and long-term performance in demanding production environments. Argus designs and manufactures these valves with stainless trim for media compatibility and low cracking pressure to reduce loss of flow.
