Medium Pressure Needle Valves

Non-rotating stem prevents galling and scoring
Five stem styles:
- Vee
- Regulating
- Metering
- Micro-Metering
- Soft Tip
17-4PH Stem for longer service life. 316 wetted parts are also available by specifying option -316WP (see page MP-3)
Glass-filled Teflon packing for temperatures to 600°F (315°C)
Integral through holes for bracket mounting, a panel-mounting option is also available (see page MP-3)
Wide range of options allow customizing of valve

BuTech Medium Pressure Valves are designed for liquid and gas flow control in petroleum, chemical, power generating and general industrial applications.

Available in a variety of body styles, the valves are designed for operation at temperatures ranging from -100° to +600°F (-73° to +315°C). Optional packings and/or extended stuffing boxes increase the range to -423° to +1200°F (-253° to +648°C).

Their rugged construction provides assurance of fail-safe operation at pressures ranging to 20,000 PSI (1380 bar).

Materials of Construction

Standard materials of construction include 316 cold-worked stainless steel, 17-4PH, Ampco 45, and glass-filled teflon. All BuTech equipment may also be produced in any machinable metal. Some of the more common exotic materials used are:

Hastelloy™
Inconel™
Titanium
Monel 400™

Tube Sizes: 1/4" through 1" ; Pressures to 20,000 PSI (1380 bar); Type: M/P Cone-and-Thread
