Sporlan OVE-30-CP100 Thermostatic Expansion Valve – 105 kW / 30 Ton, R407C

Sporlan OVE-30-CP100 is an externally equalized thermostatic expansion valve (TXV) for R407C / R22 refrigerants. With a nominal capacity of 105 kW (≈30 tons), it regulates the liquid feed to the evaporator according to the suction line superheat. It has a CP100 thermostatic charge, and thanks to its external equalizer connection it opens correctly even on evaporators with a high pressure drop.

Sporlan TXV: The Reference Valve in the Field

• 105 kW nominal capacity — verify the selection against the Sporlan capacity table for your evaporating/condensing conditions.
• Externally equalized: The design required on evaporators with a distributor and long coils.
• Replaceable power element: On Sporlan bodies the thermostatic head can be renewed separately; the charge is changed without removing the body.

Technical Specifications and Installation Notes

• Model: Sporlan OVE-30-CP100 | Type: TXV, externally equalized
• Capacity: 105 kW / ≈30 tons (nominal)
• Refrigerant: R407C / R22 | Charge: CP100
• Connection: Inlet 1 1/8" / Outlet 1 3/8" — ODF solder

• 🔧 Attach the sensing bulb to the suction line at the 3-4 o'clock position firmly and insulate it; a loose bulb makes the valve overfeed.
• Take the external equalizer line 15-20 cm downstream of the bulb, from the top of the suction line.
• Cool the body with a wet cloth during brazing — heat damages the power element charge.
• Do not move the superheat setting far from the factory value; if operation is unstable, first check the refrigerant charge and the bulb contact.
