Control valve 2-way DN 100-150mm - Cast Steel | Clorius Controls

Clorius H2F – 2-Way Control Valve DN100–DN150

The Clorius H2F DN100–DN150 is a flanged, double-seated control valve with a cast steel GP240GH / GS-C25 body. It is designed for regulating flow in high-pressure hot water, steam, and thermal oil systems, applicable in district heating, central heating systems, industrial processes, and marine installations.

Construction and Standards

• Available sizes: DN100, DN125, DN150.
• Nominal pressure: PN25.
• For DN150, PED approval is noted for PN16; PN25 is available for non-PED applications.
• Flanges conform to EN 1092-1 PN25.
• Counter flanges: DIN 2635.
• Actuator connection: G1B as per ISO 228.
• Shaft, seats, and cone: stainless steel.
• Gaskets: stainless steel sheet and copper.

Hydraulic Characteristics

The H2F features a double-seated design to reduce hydraulic forces on the shaft in larger diameters. The flow characteristic is nearly quadratic, with a control capability of Kvs/Kvr >25. Seat leakage is ≤0.5% of Kvs according to VDI/VDE 2174, thus not substituting a shut-off valve when tight isolation is required.

Kvs and Stroke

• DN100: Kvs 125 m³/h, stroke 20 mm, weight 38 kg.
• DN125: Kvs 215 m³/h, stroke 20 mm, weight 73 kg.
• DN150: Kvs 310 m³/h, stroke 20 mm, weight 76 kg.

Operation with Actuator

Without an actuator, the valve remains open via a spring. It closes with pressure on the shaft. In combination with thermostats, pneumatic or electric actuators, it can close upon temperature increase. For cooling circuits, a reverse acting electric actuator or reverse acting setup is used.

Installation

The valve can be installed with a vertical or horizontal shaft. 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.
