LATCO pressure control and relief valves are a reliable generation used for hot and cold water systems that save you time and money, offering maximum value at unbeatable prices. The Latco range of pressure control and relief valves has become the new standard in the market as pressure demands increase.


The Latco Standard Pressure Control Valve and Combined Expansion Relief Valve/Vacuum Breaker has proven time and time again its simplicity of design and reliable operation. Manufactured from a tough, corrosion resistant Acetal copolymer, Latco Standard has been in use for over 35 years on a substantial number of dwellings without change to its principal design.


The Latco Neptune valve is made from Acetal, a tried and tested material with decades of proven effectiveness in the control of potable water. Being a plastic, there is no electrolytic action with the water and no scale build up. The range of pressure regulating valves comprises 100kPa, 200kPa, 400kPa and 600kPa models.


An added benefit for South Africans is that the Latco Neptune valves have no scrap value, unlike their heavy brass equivalents; therefore there is less pilferage from merchants and building sites.


SABS specifications require a flow rate of 40 litres per minute at 200kPa pressure. The design of the Latco Neptune range easily complies with and exceeds this requirement. In addition, because the Latco Neptune uses a separate relief valve, this saves the need for one of the two vacuum breakers that must be installed with each geyser installation.


The Latco Neptune range of valves are SABS mark-bearing products, manufactured under Marley Pipe Systems’ ISO9001 rated quality management system. Each valve is individually tested before being put into stock, and consequently carries a two-year guarantee from date of manufacture. However, as our service technicians will confirm, some of our original valves made in the ‘60s and ‘70s are still going strong after all these years.
