Marine & Offshore Ball valves with firesafe approval spring washer graphite rings metallic sealing edge When handling flammable liquids, safety must be a prime concern. Great importance is therefore attributed to the design of “firesafe” shut-off valves utilized in many industrial environments including: • Chemical and petrochemical plants • Oil drilling and refineries • On- /offshore installations When fire does break out, it is important that it does not spread through failures in pipe-work systems. Even under the most extreme conditions shut-off valves must provide: • Secure operation •...

Marine & Offshore Flangeable cylinder valves for e.g. riser tensioner system • Sizes from 5/8“ to 8“ (DN15 to 200) • Pressure up to 10.000 psi (690 bar) • Steel, stainless steel or duplex • Bypass option Highly corrosion-resistant bronze marine valve • All metal parts made of nickel-aluminum-bronze • ½“ (DN13) to 8“ (DN200) • up to 420 bar (6000 psi) • Flang

Marine & Offshore Double safety & bleed (DSB) valve MHA Double Safety and Bleed valves combine various valve functions in one block. This solution is more space saving and contains much fewer potential leakage points compared to a muliple piped valve solution. Possible options for MHA DSB valves are Fig. 1: MHA Double Safety and Bleed valves ensures a two stage isolation with an integrated bleed valve at high security work areas. When maintenance service is conducted both valves are closed. Through the bleed valve the isolation of the valve can be proven. Through integra- Fig. 1: Double...

Marine & Offshore Full trunnion gas valve full trunnion capsuled PEEK • Carbon or stainless steel up to 8” (DN200) • Full trunnion design with capsuled PEEK seats • VDS tested • LRS or other classification society approvals • Manual actuation or automated solutions Valve assemblies Do you need a complete valve assembly? MHA can supply not only single valves but also complete valve assemblies that reduce the assembly time and effort for a customer’s shopfloor personnel. Upon request the assembly comes fully pressure tested or with acessories like actuators or l

Marine & Offshore Subsea ball valves In subsea applications customers need to completely rely on the equipment they use. With an exceptional quality level as well as a proven functionality, you can be guaranteed by MHA subsea valves and equipment. Subsea hot stabs • Single, dual and multiple port versions • Pressure ratings up to 1.000 bar (14,500 psi) • Various handle configurations - T-handle - Fish handle - Offset Other subsea equipment • Subsea and marine grade cylinders - Marine platform lift and level - Subsea “timing” cylidner • Complete ball valve and hot stab with receptacle...

Mining & Boring Process Industry Safety bleed valve bleed valve main valve Maintenance valve used for example in tunnel boring machines, allowing for service of cylinders without shutting down the hydraulic system. Separated shut off and bleed valve guarantees safe isolation of media in accordance with DIN EN 982 with locking device for up to 3 padlocks and bleed closed main open integrated on/off label. Normal operating position In this position the main valve is open and the bleed valve is closed. Main close position First step in locking out the hydraulic supply to the machine is to...

Renewable Energy Renewable energies play an important and growing role in the energy supply for many countries. The share of energy from renewable sources in Europe was 19,7% in 2021. A significant and growing part of that energy is generated by wind turbines. Ball valves are used in various sub systems of wind turbines. Cooling Systems Cooling systems are usually low pressure systems but due to vibration the usage of high pressure ball valves in those systems guarantees high robustness against vibrations as well as a high level of leak tightness. Hydraulic Pitch system Ball valves are used...

Construction & Agricultural Excavator grab tooling valve This valve combination is used in excavators for special tooling. Integrated safety function against overload pressure, combining ball valve, check valve and pressure relief valve in one valve block. Robust and space optimized design with fewer potential leakage points than piped solution. Examples of multi-functional valve modules Changeover block for front linkage This changeover block is mainly used in agricultural equipment. Allows for manual override of equipment movement functions. Space-saving valve block design, combining two...

Ball seat design for gas applications When the ball valve starts opening gas can cause significant damage to standard ball seats through increased flow rates. The MHA ZENTGRAF seat design with an inner metal ring protects the ball seat from erosion and increases the lifetime of the ball valve significantly. eroded ball seat standard seat design MHA ZENTGRAF gas seat design ATEX ball valves ignition source inflammable substance Explosions can cause loss of life and serious injuries as well as significant damage. The aim of the ATEX directive is both to apply a single level for health and...
