  4. R.G. Laurence Series 700 On / Off Valves

    Series 700 are pure Direct Operated valves; (referring to the internal construction) wherein the full-area valve disc is lifted off the seat against the full, static line pressure by raising the internal lever; i.e without the aid of an internal pilot and without a minimum pressure or flow requirement. The valve will open, remain open, and/or will close fully and remain closed down to 0 PSI differential. Closing speed is essentially instantaneous and independent of fluid viscosity, line pressure, or pressure drop across the valve.

  5. R.G. Laurence 2500 Series - Electrically Actuated Shutoff Valve
    Series 2500 valves are 2-way, globe-type, piston valves.They are operated by an external lever connecting the lifting action of the linear actuator to the valve piston/plug through a rotary shaft. The Rotary Shaft principle creates a mechanical advantage enabling more force in operating the valve. It also allows stronger return spring action to ensure reliable,fail-safe return. Learn More
