Forget bursting discs or a spring valve, the AKO Pressure Relief Valve is the best and most cost effective valve on the market to protect your pump or motor from over pressure and damage.
How The AKO Pressure Relief Valves work
The AKO Pressure Relief Valves are fitted onto a bypass line of a pump. The Pressure Relief Valves are then charged with air and set closed at the pressure it is required to relieve at. If the associated pump becomes clogged or blocked, causing the line pressure to exceed the pressure at which the valve is set closed at, it will open allowing the product to bypass the pump and equalise the pressure until the blockage is cleared. The Pressure Relief Valve will then reset itself in its ‘closed’ position to the original set pressure.
Natural Rubber (standard) & Nitrile (for small percentages of oil) are the most commonly used sleeves (others on request)
Accessories
Foot Pump (to inflate the Pressure Relief Valve)
Pressure switch (2 switches inside a single housing)
Pressure Relief Valves Advantages:
Pressure Relief for pumps, water, liquid, sewage/sludge and food industry
Proved reliability in the industry for over 10 years with 1000 plus applications in the UK
Clear and true bore – no blockages
No mechanical parts to get clogged or blocked
Easy and low cost maintenance
Single body casting
When the valve is set (using footpump) to the required pressure, the air supply is no longer needed – perfect for remote areas
The Valve resets itself when a blockage is cleared
No need to strip down the valve after it has relieved
No need to reset after pump starts ups or pressure surges
All Valves fully tested with unique tracking number – 100% leak tight seal
Full technical backup and valve maintenance in house or on site
General PRV Routine Maintenance
AKO UK recommend that the valves are de-pressurised every 8 weeks for a period of 15 minutes. This will ensure maximum life from the sleeve. During the same period the valve should be visually checked to ensure all parts are working. AKO advise checking the PRV evry 4 weeks to make sure it is holding pressure. It is possible that the PRV can lose up to 0.5 BAR within a 4 week period, if this occurs use the foot pump to inflate the PRV to desired pressure.
Sleeve Maintenance
AKO UK Pressure Relief Valves do not require any special maintenance. Only the sleeve is subject to wear and can be quickly replaced on site.
For further information on installation, commissioning instructions, general handling of the PRV, sleeve storage, and pressure switch safety precautions & wiring, please see the PDF PRV Information & Certificate.
