Lunkenheimer Class 150 cast stainless steel globe valves are ruggedly constructed to assure durability. Outside screw and yoke design is ideal for corrosive service. Stem threads are outside the valve, so they are free from damage by corrosive fluids and sediments. The cast grade austenitic stainless steel is in compliance with ASTM A-351 Grade CF8M.

Bodies Heavy shell thickness for strength and long lasting service.

Bonnets Body-bonnet flange faces are self-centering, male-female type, and have acid resistant gaskets. Bonnet bolting consists of through-bolts with nuts.

Yokes Integral with bonnet. Yoke bushings are durable and resistant to seizure.

Stems Rising, rotating stems have heavy Acme threads and liberal engagement with the yoke bushing for maximum strength.

Discs Standard tapered disc lifts high enough above body seat to allow full, unobstructed flow.

Seats Integral with body.

Backseat Integral with bonnet. Machined shoulder on stem seats against machined backseat in bonnet.

Stuffing boxes Deep to assure pressure tightness and long packing life. Packing is Teflon multi-filament yarn.

Flanges Flanged valve face to face length is in accordance with ANSI B16.10. Pipe flange bolt hole size and location is in accordance with ANSI B16.5 for sizes through 24 NPS. Pipe flanges have 1/16 inch raised face. Raised faces are machined to a serrated spiral finish which meets requirements of ANSI B16.5, API-600 and MSS-SP-6. Other requirements are possible.

Butt weld end Valve end to end length is in accordance with ANSI B16.10 regular (long) pattern. Unless otherwise specified on purchase order, butt weld end valves will be furnished with ends machined in accordance with ANSI B16.25 for use without backing ring or with split backing ring and to match Schedule 40 connecting pipe. Other requirements are possible.
