What Mack Valves does

Mack Valves is an Australian specialty valve manufacturer founded in 1939, headquartered in Kilsyth, Melbourne, with a secondary manufacturing facility in Pune, India. The company engineers, designs and manufactures industrial valves spanning 10mm to 600mm in size, with core technical competence in hydraulically operated diaphragm-actuated globe valves for cryogenic, steam, water, fire-protection and oxygen-service applications. Its product portfolio covers 13 core lines including the proprietary 33 Series Automatic Control Valves and 23 Series Single Diaphragm Control Valves, alongside ball valves, check valves, globe valves, liquid cylinder valves, relief valves and Y-strainers, with operating temperature ranges from -270°C to +400°C. The company holds ISO 9001/14001/45001, WaterMark AS 5081, AS4020, SSL/ActivFire, CE/PED/TPED/PESO and Australian-Made certifications, qualifying its products for safety-critical infrastructure applications.

The business operates on a quote-based, project-driven hardware sales model with three go-to-market motions: direct specialist sales for bespoke engineered solutions, an enterprise field-sales channel targeting critical infrastructure tenders, and a distributor network covering every Australian state/territory plus international distributors in Vietnam. Since 2017, Mack has operated as a majority-owned subsidiary of Germany's HEROSE GMBH (51% stake), serving as the sole Australian distributor for HEROSE's European cryogenic valve range and accessing combined group production capacity of over 400,000 valves per year. Customer concentration skews to large infrastructure and industrial accounts including the Burnley Tunnel, Domain Tunnel, Brisbane City Tunnel, Eureka Tower, CityLink Melbourne and India's iron-ore industry (500+ custom valves supplied since 2012), with custom-engineered valve solutions made from exotic materials such as Monel, High Tensile Brass and Inconel serving as a key differentiator.
