Product Description

Keraflo KP Type 4" - 100mm Inline and Variable Delayed Action Float Valve Please note delivery on KP type valves is around 6-8 weeks

Aylesbury KP type float valve kits comprises an in-line control valve together with an Aylesbury KB type float valve acting as a pilot. The pilot valve offers fully variable delayed action opening and closing water level settings, making this ideal for mains or pumped systems.

Other standout features of our Aylesbury 'KP' type float valve kits include the following:
- High Kv Value
The standard 'KP' Control Valve offers excellent flow rate performance.
Raised Valve Chamber
Can be small as it only has to accommodate a 3/4" KB valve and discharge assembly.
Facilitates Air Gaps
The Aylesbury 'KB' Valve is supplied with a 2m long adjustable chain as standard allowing the closing level to be set below any combination of  Weir Slot, Overflow and/or Warning Device.
Quiet Operation
Aylesbury valves are quieter than conventional valves due to the elimination of Water Hammer, Valve Bounce, "Hiss' and Dribble.
An externally mounted Control Valve can be easily - inspected, adjusted and if required serviced. Re-chlorination of the tank is not necessary provided the tank lid is not removed.
Optional Extra
Upstream Pressure Sustaining Regulator - the Control Valve regulates itself to leave the desired minimum upstream pressure (Adjustable 1 - 6 Bar). This can also be used to provide a constant flow rate.

No Water Hammer
Full Flow During Fill
Maximises Tank Capacity
Maintenance Free
No backing plate required
Suitable for all types of Air Gap applications
No Valve Bounce
No Dribble
Delayed Action
Tank Wall Stress negligible
Ideal for Fire Sprinkler Systems
Flexibility and ease of Installation

Conventional Float Valves above 3" are heavy and cumbersome often necessitating a two person installation. When the 'KP' Control Valve is mounted outside the tank at floor level, no heavy lifting is required.

The Control Valve can be mounted in one of four positions:
Vertically in the pipe work (preferred option)
Outside the tank at floor level
Outside the tank above the tank water level
Inside the tank above the tank water level
Multiple Discharges

To reduce the risk of stagnation, two or more discharges can be connected to the outlet of the control valve. Since the Filling Pipe is only subjected to low pressure, thin wall PVC pipe can be used. The 'KP' Valve can also be configured to service twin/partitioned tanks.

Shallow Tanks - 'KP' Valves can operate in tanks as shallow as 1 metre in depth.

Deep Tanks - The standard Aylesbury 'KB' Pilot valve enables an opening level 2m below the inlet level. A longer chain can be supplied if required.
