The Hoke Monel Gyrolok Valve is engineered for demanding industrial environments requiring secure, leak-tight performance under high pressure and temperature conditions. Constructed from Monel, an alloy renowned for its exceptional resistance to seawater, acids, alkalis, and corrosive media, this valve ensures long-term reliability and safety.

Featuring 1/2″ Gyrolok inlet and outlet connections, this valve integrates seamlessly into precision tubing systems while delivering superior vibration resistance and sealing integrity. With an operational pressure rating of 2000 psig at 70°F (138 bar at 21°C) and a broad service temperature window from –20 to +350°F (–29 to +177°C), it is well-suited for offshore platforms, chemical processing, petrochemical systems, and industrial gas handling.

Its 0.375″ (9.50 mm) flow orifice supports high flow throughput while maintaining accurate process control.
