Section 1. Introduction and Installation
Vacuum Technologies small right-angle and in-line block valves are compact
bellows-sealed valves for use in roughing and high vacuum applications. The valve body is
made of aluminum or stainless steel, and incorporates Klamp-Flange
®
, CFF or tube end
fittings to provide reliable and convenient vacuum connections. The main seal and all
vacuum seals are Viton
®
.
The valves are available in manually-operated and pneumatically-operated versions. The
pneumatic valve is also available with a position indicator. The position indicator delivers
an electrical output signal when the valve cycles, and is user-set in either the normally-open
or normally-closed position.
The NW 16 and NW 25 valves are identical except for their port sizes; therefore, all internal
spare parts are interchangeable. The NW 40 valve, however, is a larger-bodied valve
requiring different internal components.
The NW 50, NW 63 and NW 80 are available only as stainless steel, right-angle valves.
This manual contains the necessary information to install, operate and maintain the Vacuum
Technologies block valves listed in Table 1-1 and Table 1-2 on page 1-2.
