Siemens Building Technology 270-03182 Valve Assembly
The Siemens Building Technology 270-03182 Valve Assembly is a precision-engineered 2-way normally closed pneumatic valve designed for modulating control or two-position service in commercial HVACR systems. Built on the rugged Siemens Flowrite 599 Series platform, this assembly features a 1/2" NPT bronze body (UNS CA 844) paired with high-quality brass trim to ensure long-term durability in water, saturated steam, and glycol-based applications. The internal mechanisms utilize an equal percentage flow characteristic, providing stable and linear control at the lower end of the travel range, making it ideal for terminal units and small heat exchangers requiring a 2.5 Cv flow coefficient.
This unit is equipped with a 4-inch pneumatic actuator featuring a 10-15 psi spring range. The spring-return fail-safe action ensures the valve defaults to the closed position upon loss of control air, protecting downstream equipment. Rated for ANSI Class 250 service, the 270-03182 supports fluid temperatures ranging from 20°F to 250°F and offers a high rangeability of >100:1. For the service technician, the direct-coupled universal bonnet design allows for straightforward actuator maintenance without removing the valve body from the piping, while the EPDM O-ring packing provides a reliable seal against leakage.
Key Benefits
- Precision Flow Control: The equal percentage valve design ensures accurate temperature modulation and prevents hunting in hydronic loops.
- Industrial-Grade Materials: Features a corrosion-resistant bronze body and durable brass trim suitable for steam and chilled water.
- Robust Fail-Safe Protection: The normally closed pneumatic assembly automatically shuts off flow during air pressure loss to prevent system overheating or flooding.
- High Close-Off Performance: Engineered to meet ANSI Class 250 standards, providing excellent close-off ratings for high-pressure applications.
- Simplified Field Service: Designed with a universal bonnet for quick actuator coupling and standard 1/2" NPT threaded connections.
Common Questions
What is the maximum fluid temperature this valve can handle?
The assembly is rated for media temperatures between 20°F and 250°F, making it compatible with chilled water, hot water, and low-pressure steam.
Can I use this for modulating control?
Yes, the 10-15 psi spring range and equal percentage characteristic are specifically optimized for modulating applications using a pneumatic controller.
What is the fail-safe position of the 270-03182?
This is a normally closed (NC) valve; it remains closed by spring pressure and requires air pressure to open the port.
