Control valve balanced 2-way DN 15-80mm - Cast Steel | Clorius Controls

Clorius H1FBN – Balanced 2-Way Control Valve DN15–DN80

The Clorius H1FBN is a flanged, single-seated, pressure-balanced control valve with a cast steel GP240GH / GS-C25 body. It is used for hot water, steam, and thermal oil applications where differential pressure requires greater closing force than a simple single-seated valve can provide.

Technical Specifications

• Actuator connection: G1B per ISO 228.
• Seat, cone, and stem: stainless steel.
• O-ring: A75H FEPM.
• Gasket: stainless steel sheet.
• Flow characteristic: quadratic.
• Seat leakage: ≤0.05% of Kvs per VDI/VDE 2174.
• Control range: Kvs/Kvr >25.

Kvs and Stroke

DN15: Kvs 4 m³/h, stroke 7.5 mm.
DN20: Kvs 6.3 m³/h, stroke 7.5 mm.
DN25: Kvs 10 m³/h, stroke 9 mm.
DN32: Kvs 16 m³/h, stroke 10 mm.
DN40: Kvs 25 m³/h, stroke 11 mm.
DN50: Kvs 35 m³/h, stroke 11.5 mm.
DN65: Kvs 58 m³/h, stroke 14.5 mm.
DN80: Kvs 80 m³/h, stroke 16 mm.

Operation

Without an actuator, the valve remains open via a spring. It closes with force applied to the stem. With a thermostat, pneumatic, or electric actuator, it can close upon temperature increase. Cooling circuits require a reverse-acting electric actuator.

Applications

• Steam or hot water exchangers,
• district heating and central heating systems,
• thermal oils in industrial skids,
• marine installations,
• processes requiring low seat leakage and PN40 body.

Installation

Installation can be vertical or horizontal. Up to 170°C, the thermostat or actuator can be mounted above or below the valve. Above 170°C, a cooling unit for the thermostat or a high-temperature adaptor for the electric actuator is required.
