Description
Belimo B315 3-Way Ball Valve Overview
The Belimo B315 is a precision-engineered 3-way ball valve designed for reliable flow control in chilled water and hot water HVAC systems. Built with a nickel-plated forged brass body and a stainless steel ball and stem, this valve delivers exceptional durability and corrosion resistance in demanding hydronic applications. With a maximum operating temperature of 250°F, it is well-suited for both heating and cooling coil control in commercial and industrial HVAC systems.
Key Features
- 3-way ball valve configuration for mixing or diverting applications
- 1/2″ NPT connections for straightforward installation into standard piping
- 10 Cv flow coefficient for precise, high-capacity flow control
- A-port: Equal Percentage flow characteristic for accurate modulating control
- B-port: Modified flow characteristic for constant common port flow
- Nickel-plated forged brass body for superior corrosion resistance and long service life
- Stainless steel ball and stem for durability and reliable sealing performance
- Rated for chilled water and hot water service up to 250°F maximum
Flow Characteristics
The B315 features dual flow characteristics engineered for optimal system performance. The A-port delivers an equal percentage flow characteristic, providing fine modulating control across the full stroke range — ideal for coil control applications where precise temperature regulation is required. The B-port is modified to maintain constant flow through the common port, ensuring balanced hydronic system performance.
