262-02067 Siemens Valve Assembly

The Siemens 262-02067 3WMX,LN,BZ,OR, FXF ,0.5/1.6

Overview

The Siemens 262-02067 is a Powermite 599 MT Series three-way mixing globe valve assembly designed for precise control in commercial heating and cooling applications. It features an electronic, spring-return actuator that provides fail-safe modulation, making it ideal for managing the flow of hot or chilled water, as well as glycol solutions up to 50% in demanding industrial and building technology environments.

Features

• Designed with a direct-coupled universal bonnet for easy installation without complex tools.
• Incorporates a spring-return electronic actuator for reliable fail-safe operation during power loss.
• Built with a heavy-duty forged brass body and robust brass trim to maximize service life and withstand wear.
• Utilizes manual override with an automatic unlock mechanism for simplified maintenance and service.
• Offers precise modulating control via a 0-10 VDC analog signal to maintain consistent temperature regulation.
