MWH Offers High-Quality,
Inlet And Exhaust Valves
For Marine Engine Applications
—Color Brochure Available—
West Germany-based Markisches
Werk Halver (MWH) has more than
50 years' experience in the design
and production of high-quality inlet
and exhaust valves. MWH offers a
complete range of valves, valve
cages, valve rotators, accessories
and complete exhaust valve assem-
blies for diesel engines in ship pro-
pulsion and generator applications.
Two characteristics of the compa-
ny's products are high quality and
precision manufacturing, both of
which result in a longer service life,
lower maintenance costs and higher
profitability for MWH customers.
Specially designed modifications
and general improvements are con-
stantly introduced by MWH engi-
neers in an effort to increase cost-
effectiveness for the company's cus-
tomers. Examples of this, according
to MWH, are its improvements in
the area of cylinder heads for gas
engines and in its development of
Nimonic valves.
MWH reports that its bi-metal
Nimonic valves have proven to be
the best solution for heavy fuel op-
eration use because they show bet-
ter resistance against corrosion and
high material strength at high tem-
peratures. MWH Nimonic valves
have already been in use for over
20,000 running hours.
To protect against corrosion,
MWH valves are chromed, nitrided,
coated with Molybdenum or other
special alloys. The company has de-
veloped special techniques to polish
the valves so as to take account of all
the special forces and gas flows to
which the valves are exposed during
operation.
Markisches Werk maintains strict
manufacturing and production con-
trols to ensure the quality of its
products. These controls begin with
the receipt of the raw materials.
Each shipment is checked against
the requested nominal values. In
case where these values are not
achieved, the shipment is rejected.
During the manufacturing pro-
cess, each worker checks and con-
trols his own work. MWH reports
that this system has proven to be a
highly successful practice for main-
taining quality standards.
In addition, MWH's modern pro-
cess equipment ensures a quality
product. Each piece is checked 100
percent before it is packed for ship-
ment. This checking includes, of
course, crack testing by fluorescent
penetrants.
Quality assurance is the direct
responsibility of senior management
as well as line management. This
ensures tight control and underlines
the importance given to quality as-
surance at MWH.
The company's new laser marking
machine protects against imitation
and also reduces cost.
MWH also has developed water-
cooled exhaust valve cages. The
cooling water flows a few millime-
ters from the valve seat, substantial-
ly reducing temperature. Conse-
quently, the service life of the valve
spindle and valve cage are in-
creased.
Another area where MWH's pre-
cision engineering is of particular
importance is in the supply of com-
plete valve assemblies. All compo-
nents are specifically made to
achieve the best match possible.
The company also offers a new
valve cage reconditioning service.
The valve cages are first checked in
order to determine if the repair is
economically viable. Repair work is
carried out at the company's facili-
ties. MWH can also supply recondi-
tioned cages on an exchange basis.
