Belimo B254 Ball Valve

The Belimo B254 is a professional-grade 2-way characterized control valve designed for precision modulation in hydronic systems. Featuring a 2-inch NPT connection and a robust 240 Cv rating, this valve is engineered for high-flow chilled or hot water applications. The assembly utilizes a nickel-plated forged brass body integrated with a 304 stainless steel ball and stem to ensure long-term durability and resistance to scaling. Its equal percentage flow characteristic is achieved via a specialized Tefzel characterizing disc, providing linear heat output and stable control loop performance. Rated for media temperatures up to 212°F and compatible with up to 60% glycol solutions, this DN50 ball valve is the standard for contractors requiring reliable HVAC control valve replacements. The blowout-proof stem design and double O-ring seal provide a maintenance-free solution for demanding commercial mechanical rooms.

• Precision Flow Control: The integratedizing disc ensures an equal percentage flow for optimized heat exchanger efficiency.
• High Durability: Stainless steel ball and stem prevent corrosion and premature failure in aggressive fluid environments.
• Maximum Versatility: High close-off pressure rating of 200 psi ensures tight shut-off even in high-head applications.
• Low Torque Requirements: Precision machining allows for the use of smaller, more cost-effective Belimo actuators.
• Leak Protection: Double EPDM O-ring stem seals prevent hydronic system fluid loss and air infiltration.

What actuators are compatible with the Belimo B254?
The B254 is designed to pair with ARB, GRB, and AF series non-spring return or spring return actuators, depending on your fail-safe requirements.

Can this valve be used in steam applications?
No, the B254 is specifically rated for chilled or hot water and glycol solutions up to 212°F; it is not intended for steam service.

What is the maximum differential pressure for this 2-inch valve?
The maximum differential pressure for modulation is 30 psi, while the close-off pressure is rated at 200 psi.
