Siemens Building Technology 257-02036 Valve Assembly
The Siemens Building Technology 257-02036 Valve Assembly is a heavy-duty industrial solution designed for precise terminal unit control in hydronic systems. This 2-way normally open pneumatic valve features a 1/2-inch NPT connection and a 1.6 Cv rating, utilizing a modified equal percentage flow characteristic to ensure stable linear heat output in heating and cooling applications. The assembly integrates a rugged forged brass body with a reliable brass trim, paired with a 2-inch pneumatic actuator that operates within a 3-8 PSI spring range. Engineered as part of the Powermite 599 MT Series, it is rated for ANSI Class 250 pressure requirements, making it a standard choice for contractors managing hot water, chilled water, or 50% water-glycol solutions. The normally open configuration ensures a fail-safe flow in the event of pneumatic signal loss, maintaining system circulation. Its compact footprint and direct-coupled design allow for streamlined installation in tight mechanical cabinets and plenum spaces.
Key Benefits- Precise Flow Modulation: The 1.6 Cv with equal percentage characteristic prevents hunting and provides superior temperature stability.
- Industrial Durability: The forged brass body and brass trim are designed to handle medium temperatures from 35°F to 250°F.
- Reliable Fail-Safe: The normally open operation ensures the valve defaults to the open position during a signal failure.
- Simplified Maintenance: Part of the Siemens 599 Series, allowing for easy field replacement of the pneumatic actuator or valve internal components.
- High Pressure Rating: Built to ANSI Class 250 standards to withstand demanding commercial HVACR environments.
What is the maximum pressure rating for this assembly?
The assembly is designed to ANSI Class 250 specifications, typically supporting up to 400 psi at lower temperatures and 125 psi WOG in standard HVAC applications.
Can this valve be used for steam applications?
This specific model features brass trim; while it is rated for hot water and glycol, stainless steel trim is generally recommended for saturated steam service up to 15 psi.
Is the actuator replaceable without removing the valve body?
Yes, the pneumatic actuator is direct-coupled and can be serviced or replaced without breaking the pipe connections, saving significant labor time.
