In 1945 Alfred Zentgraf founded a mechanical engineering company and by 1978 the company began specialising in valves and high-pressure ball valves for which is best known. MHA Zentgraf now have presence in Europe, America and Asia and their products cover a range of industries including automotive, construction and agriculture, fire protection, oil and gas, mining, energy and renewables.
MHA Zentgraf is one of Europe's leading manufacturers of ball and flow control valves for use with high pressure hydraulic applications. The MHA range of valves has a proven track record for ultra-high pressure applications up to 800 bar (11,600 psi). Ball valve performance to the highest standards has been achieved and is maintained by using superior quality MHA specified materials.
In order to provide the many advantages of ball valves in high temperature applications, MHA has developed the MKHT series of ball valves. These valves are designed with a gland packing of special material. This sealing allows applications with high pressure and simultaneously high temperatures. MHA shut-off valves are designed to function safely in extreme conditions providing:
Stainless steel and carbon steel construction
Galvanic Chrome-VI free surface plating - "MHA-Protect"
Secure operation
Reliable sealing in shut-off position and to the outside
MNA Zentgraf is certified according to the Pressure Equipment Directive (CE) and DIN EN ISO 9001 : 2000.
