The 1100 Series valves are designed specifically for the dosing industry to meet the needs of dosing pump manufacturers, dosing system builders, and end users in terms of reliable operation, flexibility, and safety. They are available in PVC, PP, PVDF, PTFE, 316, Hastelloy, Titanium, and Carpenter 20. Optional features can be incorporated including vent alarm, security locks, manual lift etc.. and the valves are available to match all types of connections and pipework standards.

The size and capacity ranges available provide adequate flexibility to match virtually any pump or system throughput whilst retaining uniformity of design, operational familiarity, and - when required - spares. The valves operate on the spring loaded diaphragm principle and although designed initially for use within dosing systems they are equally suited to installation on any other pressure relief or loading duty consistent with their type and design..

APPLICATIONS
Pressure relief of dosing lines.
Pressure sustaining (loading) for dosing pumps.
Pressure relief for P.C. or other positive displacement pumps.
Flow checking (where supply pressure is higher than pumped discharge pressure).
Anti-siphoning.
Combination back pressure & check valve.
Backpressure valving.
Pump re-cycle bypass relief.
Thermal expansion relief.

INFORMATION REQUIRED FOR QUOTATION
1) Pumped fluid details and flowrate (advise if damped or not).
2) Standard valve or special options required?
3) Type of connections required (and size of pipework if existing).
4) Any preferred construction materials.
5) Required relief or loading pressure if required for factory setting.
