Arrow Valves


Break Tank assembly with Fluid Category 5 protection by virtue of the integral Type AB air gap. The unit is supplied as a complete package on a base plate ready for installation.

The primary purpose is to provide backflow protection in accordance with the new Water Regulations. The BTAB unit also boosts the water pressure for elevated areas or where a high flow rate is required – e.g. wash-down.


Wall mounted break tank and pump assembly with Fluid Category 5 protection by virtue of the integral Type AB air gap complying with BS EN13077: 2003. The set is housed in a stainless steel cabinet – with drainage holes in its base – ready for wall mounting in a frost free environment.

The primary purpose is to provide backflow protection in accordance with the new Water Regulations. The Midi unit also provides cold water at a known outlet pressure.


Compact booster pump set designed to boost pressure for tall buildings where the mains supply is inadequate e.g. penthouse suites.

The unit is supplied as a complete package on a stainless steel base plate ready for installation. The set is approved for drinking (Wholesome) water applications since it has a screened overflow and vent – conforms to G16.13.

The primary purpose is to boost the water pressure for elevated areas or where a high flow rate is required – e.g. for showers and baths.

Ablution Plant

The Ablution Plant unit delivers hot water at the required temperature with the highest backflow protection. The primary application is bidets or ablution hoses adjacent to a WC or bidet. The unit can also be used for many other applications requiring hot water with Fluid Category 5 protection.

Toiletry applications are strictly Fluid Category 5, requiring a point of use air gap from the mains water or building supply pipe. There is a duty of care to provide warm water at a safe temperature with suitable legionella controls in place.

Care Shower

The Arrow Valves Care Shower is a special thermostatic electric shower (meeting BEAB Care Mark requirements as being safe for use by elderly, young and sick) and Booster Pump package (model CSABATLF).

The assembly has Fluid Category 5 backflow protection via integral AB air gap with booster pump and is therefore suitable for the highest risk applications.

Aylesbury ‘K’ Type

– Delayed Action Float Valve
– Suitable for tanks without raised valve chambers

The weighted key-shaped float can be accurately set in a number of positions on the brass float arm, actuating the valve at a predetermined difference in water level, driving it fully open or fully closed without water hammer.

This positive action avoids dribble, reduces noise and allows full flow until the selected level is reached. Inherent in the design is a non-adjustable operating differential in water level between opening and closing of approximately 75mm. Also available in stainless steel as KS Type 

Aylesbury ‘KAX’ Type

– Delayed Action Float Valve
– Primarily for tanks with raised valve chambers

Identical in operation to the ‘K’ Type, the Aylesbury ‘KAX’ Type Valves have extended drops and are suitable for raised valve chambers. They are primarily designed to fit into chambers or boxes in the covers of tanks calling for Air Gaps or where maximum tank capacity is required.

To assist with compliance of Air Gap requirements the valve discharge is further raised above the centre line. The ‘KAX’ is especially suitable for Type AA & AB Air Gaps.

Aylesbury ‘KB’ Type

– Fully Variable Delayed Action Float Valve

– Suitable for tanks with or without raised valve chambers

The valve is operated by a transfer of weight in an actuator tube which causes the valve to open or close. The arrangement of the float and buoy assembly produces a delayed change of balance in the actuator as the water level alters. The total assembly is relatively light with no pressure related stresses. As a result the valve does not require any supporting structure.

Aylesbury ‘KB’ Type valves have a variable delayed action and feature a chain in place of a rigid float arm enabling virtually unlimited opening and closing levels. This allows for a considerable drop from the valve to the water level, overcoming issues associated with drop arms.

The versatility of the Aylesbury ‘KB’ Type makes it suitable for installation either directly into a tank or into a raised valve chamber particularly where Air Gaps are required. Changes in water levels and differentials can be made quickly by the installer or maintenance engineer without tools.

This feature is particularly useful where water demand changes either due to seasonal factors, building occupancy or where the commissioning of a facility is phased, as it reduces the risks associated with excess water being stored for too long.

Aylesbury ‘KP’ Type

– Fully Variable Delayed Action Float Valve, 

– Suitable for use with large tanks or high flow rates

– Suitable for tanks with and without raised valve chambers

The ‘KP’ Type Float Valve Kit comprises an in-line control valve together with an Aylesbury ‘KB’ Type Valve acting as a pilot. The pilot valve offers fully variable delayed action opening and closing water level settings and on/off operation making this ideal for mains or pumped systems.
