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.

Figure 2. Close-off Pressures.
Operation Figure 3 shows the normally open valve in the open or full flow position and the
normally closed valve in the closed or zero flow position. The valve spring provides the
necessary force to hold the stem in the raised or normal position.
In the event of power failure, a spring return actuator returns the valve to its normal
position. Non-spring return actuators will hold the last commanded position. See the
Technical Instructions of the various actuators for additional information.

Figure 3.
Sizing The sizing of a valve is important for correct system operation. An undersized valve will
not have sufficient capacity at maximum load. An oversized valve can initiate cycling,
and the seat and throttling plug can be damaged because of the restricted opening.
Correct sizing of the control valve for actual expected conditions is considered essential
for good control.
See Tables 3 through 6 for valve capacities.

Document Number 155-196P25

Siemens Building Technologies, Inc. Page 9
Sizing, continued The following variables must be determined:
•The medium to be controlled: water, etc.
•The maximum inlet temperature and pressure of the medium at the valve.
•The pressure differential that will exist across the valve under maximum load
demand.
•The maximum capacity the valve must deliver.
•The maximum line pressure differential the valve actuator must close against.
See Application Bulletin (AB)-1 Control Valve Selection and Sizing (155-285) for further
recommendations.
Mounting and
Installation Install the valve so that the flow follows the direction of the arrow indicated on the valve
body.
For best performance, install the valve assembly with the actuator above the valve body.
The valve and actuator can be installed in any position between vertical and horizontal. It is
not recommended to install the valve assembly so that the actuator is below horizontal or
upside-down.
Allow sufficient space for servicing the valve and actuator. See Table 11 for valve body
dimensions. See Figure 4 and Table 10 for dimensions of the service envelope
recommended around the actuator.
NOTE: Instructions for field mounting an actuator, wiring diagrams, and start-up are
covered in the Technical Instructions and Installation Instructions for each
actuator.
