1100 Series pressure loading-valves are designed specifically for the dosing industry. They are used by dosing pump manufacturers and dosing system manufacturers, and offer reliable, flexible and safe operation for end-users.

Valve types

The valves can be made in PVC, PP, PVDF, PTFE, stainless steel (316), hastelloy, titanium and Carpenter 20.

Optional features include vent alarm, security locks and manual lifts. Valves are available to suit all types of connections and pipework standards.

Size and capacity

The 1100 Series is available in sizes and capacities to suit virtually any pump or system throughput, without compromising the original design or operation.

The valves operate on the spring-loaded diaphragm principle, and although designed for use in dosing systems, they can also be installed on other pressure loading systems.

Applications

  • Pressure relief of dosing lines

  • Pressure sustaining (loading) for dosing pumps

  • Pressure relief for progressive cavity or other positive displacement pumps

  • Flow checking (where supply pressure is higher than pumped discharge pressure)

  • Anti-siphoning

  • Combination back pressure and check valve

  • Back pressure valving

  • Pump re-cycle bypass relief

  • Thermal expansion relief
