MT Series Terminal Unit

Two-way Valves

Siemens Building Technologies, 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.

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.

NORMALLY OPEN

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.

Powermite 599 MT Series Terminal Unit 2-way Valves Technical Instructions

Document Number 155-196P25

April 9, 2009

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.
