MT Series Terminal Unit 2-Way Valves
Siemens Building Technologies, 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)
