Fine Metering Valves From

Nupro Offer Improved

Stability & Flow Control

Nupro Company of Willoughby,

Ohio, has available fine metering valves, redesigned for better flow control and longer cycle life. The valves also have a more compact design with fewer components.

Long-term reliability is an impor- tant benefit. Stem threads, for ex- ample, are removed from system fluids by an O-Ring seal that also eliminates the need for packings and adjustments. The orifice and tapered needle are protected from damage by a guide O-Ring that allows the stem to "float" within the body. A body seal prevents leakage to atmosphere.

Valves are available in brass,

Monel® and 316 stainless steel. 0-

Ring materials include Viton®,

Buna, neoprene, silicone and ethyl- ene propylene. Kalrez® 0-Rings and

TFE body seals for use with corro- sive system fluids are optional. Also optional are vernier handles for re- peatable flow adjustment.

Maximum pressure rating is 2,000 psi. Temperatures range from — 10°F to 300°F for brass valves and —10°F to 400°F for stainless steel and Monel valves.

Swagelok tube fitting and pipe end connections from ^-inch to Vi - inch.

Sparrows Point Yard

Wins Repair Contract

For 'Energy Independence'

The Sparrows Point Shipyard of

Bethlehem Steel Corporation has been awarded a major contract for the repair of the S.S. Energy Inde- pendence, according to David

Watson, general manager.

The 666-foot-long coal carrier, owned by the New England Collier

Company in Philadelphia, Pa., en- tered the yard recently for an ap- proximate 40-day duration while the engine's main drive gear is re-

Circle 342 on Reader Service Card moved and replaced with a new gear, Mr. Watson said. The cost of the job was not disclosed.

Mr. Watson said the work will be complicated and represents one of the first quick turnaround repair projects lined up by the yard, which has historically been involved in long-term new buildings and recon- struction.

The general manager said em- ployee levels have been declining recently while the yard prepares for the construction start of two U.S.

Navy T-AGS oceanographic survey ships, expected to begin in January.

Work on this ship will help maintain the present workforce level of 1,200.

The S.S. Energy Independence, one of the only American-flag ships afloat capable of using coal or oil for fuel, carries coal throughout the northeast and calls frequently on the Port of Baltimore. The ship is 95 feet wide, 56 feet deep and powered by General Electric steam turbines and gears.

In addition to this job, the yard began the fabrication this month of a 310-foot-long container barge for the Hale Container Line, Inc. of

Baltimore.

PROVEN

Flawlessly surpassing the trial of time.

In a marine engine, dependability is an obvious benefit.

The dependability that keeps an engine running day in and day out, in all conditions, offers safety advantages that are obvious to those who go to sea.

The dependability that keeps a vessel in service, doing its job, run after run, free of downtime, has rewards that are obvi- ous to those who mind the bottom line.

For over 75 years Volvo Penta Marine engines have proven they can deliver that kind of time-tested dependability.

But there's another definition of de- pendability, not so obvious, but vital to the profitable operation of any working craft or fleet of working craft. And that's dependability when it comes to service and support.

It begins with the installation. We put all of our experience at your disposal, from the correct engine specs to pro- peller calculations, from choice of hydraulic equipment and power take-off dimensioning to speed and torque requirements.

When it comes to maintenance we understand that time spent waiting is money lost. That's why we stock a full line of spare parts at convenient locations all around the country, ready to be deliv- ered when you need them. In addition,

Volvo Penta technicians are always on hand to solve particular problems.

At Volvo Penta we build a complete line of diesel engines for workboats, from 60 h p. to 400 h p. Including turbo- charged and aftercooled models that boost power and efficiency potential.

Volvo Penta has made a firm commit- ment to back up its investment in the

North American Marine Industry. A commitment that has built an outstand- ing network of service and support. A system that is your guarantee that we'll be here tomorrow to back up what we sell today. VOLVO
