Diamond Valves
Trusted hygienic stainless steel valves, that are fully maintainable
From food processing to pharmaceuticals, Diamond valves provide the highest performance standards.
When you choose DPL for your Diamond valves, you get:
- Expert advice to help you choose the right Diamond valves for your application
- Guaranteed compatibility thanks to our wide range of end connections
- Clear traceability of parts and spares thanks to our dedicated valve coding
- Actuators and switch boxes for central computer control to meet your control requirements
Diamond Single Seat Valves
The Diamond shut off and divert range of Single Seat valves is advanced, modular and upgradable to suit your requirements.
ATEX approved Version Available – Enquire for more details!
The most common valve configurations are shown above. Many other configurations and orientations are available. Please contact DPL for further help and advice.
As standard, the valves are fitted with the spring return actuator closing the valve spindle downwards with the spring, this is termed normally closed (NC). The valves can be fitted with the actuator opening the valve spindle upwards with the spring, this is termed normally open (NO). The actuator is easily field reversible for NC or NO.
ATEX approved version available for use in potentially explosive atmospheres.

Diamond Series 3 Pressure Relief Valves
Designed to meet the changing needs of the process industry, the new Series 3 Pressure Relief valve uses elements of the DPL single and double seat valves to produce a full bore, self draining device ranging in size from 1-4”.
Available in manual and actuated format, the Series 3 valves have a tamper-proof pressure setting mechanism which can be adjusted in-line.
The valve can be disassembled for servicing without affecting the factory pressure setting.
Group use according to the Pressure Equipment Directive
With regard to the Pressure Equipment Directive (PED) the Pressure Relief Valves produced by DPL are designated as manufactured to Sound Engineering Practice (not to be CE marked). The valves are for use with piping media content within Group 2 and a pressure range 0 to 10 bar g.
Accordingly DPL valves are marked with the relevant directive number and S.E.P.
Working temperatures dependent upon choice of seal material, please consult DPL if in doubt
