Powermite 599, ANSI Class 250

MT Series Terminal Unit 2-Way Valves

Siemens Industry, Inc.

Description

The Powermite 599 Series ANSI Class 250 MT Series

2-way valve bodies work with any MT Series pneumatic or

electronic actuator with a 7/32-inch (5.5-mm) stroke. They

are suitable for normally open or normally closed control.

Typical applications include control of hot or chilled water,

water-glycol solutions up to 50% and steam up to 15 psi

(steam only with stainless steel trim). Compatible

actuators deliver a minimum of 67 lbs (300 N) of force.

Features

• Direct-coupled universal bonnet

• Female NPT end connections with either brass trim or

stainless steel trim.

• ANSI Leakage Class IV (0.01% of Cv)

Product Numbers

Use the product numbers in the tables to order the valve

and the actuator assembled together. The product number

consists of a 3-digit prefix code, a hyphen, and a 5-digit

suffix code. The prefix specifies an actuator. The suffix

specifies the valve body.
