Our Products / Brands / Stubbe / DHV712-R

As of September 2013, the Stubbe range of Thermoplastic Pressure Relief/Sustaining valves has been rationalised. So, instead of models DHV715-716-725, only model DHV-712-R will be produced as it performs the same functions, covers a similar pressure range (0.3-10 bar) and performs better. The external components are the same dimensionally so you can remove the body section from one of the older models, replace with DHV712-R and retighten using the existing end connectors and union nuts.

Significant stocks of DHV716 are still available in our Osborne Park Warehouse and spare parts for the superseded models will still be available for some time. Over the next few months, the new model will gradually replace the older ones.

The patented DHV712-R is unique and was designed specifically for chemical plant manufacture, for water treatment and for use in electroplating plants. The internal piston also offers the additional function of non-return. The valve also performs well in vibrating environments, even behind oscillating dosing pumps.

Stubbe Thermoplastic valve used for pressure relief, overflow or bypass but also sensitive/accurate enough to be used as an upstream pressure sustaining valve or back pressure regulator, UPVC body, PTFE coated diaphragm, EPDM or FPM seat & seals, true union style body with solvent weld ends to BS/Ansi dimensions – rated 10 bar. The internal piston also performs as a non-return valve
