MT Series Terminal Unit
Two-way Valves

Siemens Industry, Inc.

Description

The Powermite 599 Series ANSI Class 250 MT Series two-way valve bodies work with
any MT Series pneumatic or electronic actuator with a 7/32-inch (5.5 mm) stroke.

Features

• Direct coupled universal bonnet

• Choice of brass or stainless steel trim

• ANSI Leakage Class IV (0.01% of Cv)

Application

A typical application for the Powermite two-way valve is the control of hot or chilled
water or low pressure (<15 psi with stainless steel trim only) steam for convectors, fan
coil units, unit conditioners, radiation, reheat coils, and similar terminal units requiring
an actuator that delivers a minimum of 67 pounds force (300 N).

Product Numbers

See Table 2.

Ordering a Valve
Plus Actuator
Assembly

To order a complete valve plus actuator assembly from the factory, combine the
actuator prefix code with the suffix of the valve assembly product number. See
Technical Bulletin TB251 (155-306P25) for selection procedure and ordering codes.

Valve assemblies can be ordered using the numbers in Table 2.
