Siemens Building Technology 268-03167 Valve Assembly
The Siemens Building Technology 268-03167 Valve Assembly is a heavy-duty 2-way normally open globe valve engineered for precise control in hydronic systems and saturated steam applications. This 1-inch NPT valve features a 10 Cv equal percentage flow characteristic, ensuring stable modulation and linear heat transfer across varying load conditions. Built with a UNS CA 844 bronze body and brass trim, the assembly is rated for ANSI Class 250 service, capable of handling medium temperatures from 20°F to 250°F. The integrated 4-inch pneumatic actuator operates on a 3-8 psi spring range, providing reliable fail-safe open positioning upon loss of control air. As a Flowrite 599 series component, this assembly utilizes a stainless steel stem and EPDM O-ring packing to maintain a Class IV leakage rate, preventing energy loss in high-demand mechanical rooms. This is a standard-duty solution for contractors requiring direct-coupled pneumatic control valves for building automation integration.
Key Benefits- Precise Throttling: The 10 Cv equal percentage plug design provides logarithmic flow increases for superior control over hot water and steam coils.
- Physical Durability: The bronze valve body and 303 stainless steel stem withstand corrosive environments and high system pressures up to 250 psi.
- Field Reliability: A 3-8 psi pneumatic actuator ensures predictable normally open performance without the complexity of electronic fail-safes.
- Tight Shut-off: Achieves ANSI Class IV leakage (0.01% of Cv) using metal-to-metal seating, ideal for reducing "ghost" energy loads.
What is the maximum operating temperature for this Siemens assembly?
This globe valve assembly is rated for fluid and steam temperatures between 20°F and 250°F, covering most standard HVAC and low-pressure steam requirements.
Is the 268-03167 suitable for steam applications?
Yes, the brass trim and bronze construction are compatible with saturated steam, provided the pressure and temperature remain within the 250 psi and 250°F limits.
Does this unit include the pneumatic actuator?
Absolutely. The Siemens 268-03167 is a complete valve and actuator assembly, featuring a factory-mounted 4-inch pneumatic head with a 1/8-inch NPT air connection.
