Tapflo UK Ltd. offer more than just diaphragm pumps, we are all about your flow. As a result, we have an extensive range of control, safety and isolating valves to complement our vast range of industrial and hygienic pumps. All valves can be supplied manually operated however we can also supply valves electrically or pneumatically actuated for remote control operation. WRAS Approved, API, Gas Approved, Anti-Static & Firesafe Valves are also available on request. Data Sheets, CAD & STEP Files are available on request as well as handle printing. Below is a table demonstrating the selection of valve types, materials & sizes we can supply.

Valve Information & uses

Valve Type Info & Use
Ball Valve Ball valves

- Can be used for Isolation & Regulation

- When positive shut-off is required

- Where a compact design is required

- Quick opening – 90º rotation between open to fully closed

- Handle positioning is a quick indication as to whether the valve is open or not

- Full bore designs do not restrict flow

Butterfly Valve butterfly valves

- When positive shut-off is required

- Mainly used for Isolation however can also be used for Regulation

- Quick opening – 90º rotation between open to fully closed

- Lightweight & Easy to install - fit between flanges in pipework

- Less costly than Cast Iron Bodied Gate Valve equivalents

- Can be used for slurries and where there are solids in suspension

- Restrict flow even when fully opened – disc is sat in fluid path.

Gate Valve gate valves

- Only used for Isolation

- Minimal Pressure Drop

- Minimal Fluid Entrapment

- Used for intermittent and occasional operation

- Slow to open and close due to rising stem/gate

Check Valve check valves

- Used for controlling direction of flow and preventing back flow

- Swing Check Valves are used where minimal pressure drop is required & recommended for use with Gate Valves

- Can only work in certain mounting configurations as they rely on gravity to re-seat

- Spring Check Valves are used with reciprocating pumps and can be used in all mounting positions

Globe Valves globe valves

- For Regulation of Flow & frequent operation, short stems reduce operating time

- Introduce appreciable pressure drop

- Fairly bulky & heavy
