TOV – F Double Flanged high performance Triple Offset Butterfly Valve

TRIPLE OFFSETA high performance butterfly valve. This valve has three offsets from the centre. The third offset is the elliptical seat geometry. This along with the two eccentric shaft offsets, allows the disc to seal against the seat with no friction.

This seat design allows for uniform sealing, and thus bi-directional tightness at maximum differential pressure.

This triple eccentric design is a lower cost, lower torque option, than alternative style metal seated valves. It is low maintenance and offers an extended valve life.

The triple offset butterfly valve is used in critical demanding applications in:

• Oil & Gas• Petrochemical• Power Generation• Process & Chemicals• Water & Wastewater Treatment• Marine

‘P’ Series actuators cover the large end of the torque range. These all incorporate a body of cast aluminium and have steel for the rack on pinion drive. Spring return versions have a maximum of 14 springs 7 in each end cap assembled within a hexagon pattern.

Options:

• Double Acting Actuator• Single Acting Actuator• Actuator with carbon steel housing for

offshore/arduous duties • Actuator with 180° rotation • Three position Actuator• Limit stops in the end caps• Limit stop with Limit stop plate• Actuator with ±3° extra travel • Full system supply including

switchboxes, solenoid valves, positioners etc.

AIR VACUUM VALVESFrenstar offer Air Valves from our dedicated factory to the finest quality.

Our UK manufactured air valves are tailored for the global oil and gas, petrochemical and marine sectors. The materials available are compliant and offer outstanding protection for severe offshore environments and seawater service. We utilise UK foundries that are Norsok M-650 approved and any raw materials are from within the UK / EU.

Air release valves are used in pressurised pipe work systems to vent off unwanted air within them. Trapped air rises and collects within the high points of the system. Air vented water fills the valve, raising the float until the valve seat is pushed back against the orifice closing it off from atmosphere again.

WHY USE AIR VALVES?• Single function (Air Release)• Bi functional (Vent & Vacuum)• Tri functional (Combination)

Frenstar provides an automatic air exhaust function on the valve so as to avoid creating water hammer in the pipeline.

An automatic exhaust of air in the pipeline will prevent the pipeline being damaged by an air pocket and ensure smooth water flow.

Material testing is available to NORSOK MDS, TR2000, individual company or project requirements.
