Sporlan HVE Series

The Sporlan HVE is a Type H body thermostatic expansion valve for R-22 duty with external equalization — decoded per Sporlan nomenclature as H (body type) + V (refrigerant code for R-22 family, green colour code) + E (external equalizer). The Type H is one of Sporlan's classic large-capacity flanged valve bodies, re-rated to ARI Standard 750 and in continuous industrial service for decades — which is precisely why HVE valves remain a staple of the Indian replacement market for R-22 cold storage and process plants.

Sporlan TEVs regulate liquid refrigerant injection into the evaporator, controlled by superheat. Core Sporlan engineering carries across the range: a large flat diaphragm for precise valve control, field-replaceable thermostatic elements, precise pin-and-port alignment for tight seating, and external superheat adjustment on all standard valves.

Nominal capacities available: HVE-5-1/2, HVE-7, HVE-11, HVE-16 and HVE-20 — the number is nominal tons on R-22, not the connection size.

Thermostatic charge — the suffix, and the part most enquiries leave out. The letters after the tonnage are the charge, not the orifice: C (liquid charge, commercial refrigeration), CP100 (gas-cross charge with MOP around 100 psig, air conditioning and heat pump), GA (gas-cross pressure-limiting, anti-hunt), Z (liquid-cross, low temperature) and ZP40 (Z charge with MOP). A complete order reads like HVE-16-CP100.

Connections are ordered separately. Type H valves ship "less connections" — the ODF solder or FPT flange kit is a separate line item. Tell us the tonnage, the charge and the line sizes and we will quote the valve and the flanges together so nothing arrives incomplete.

Fit an HVE when an R-22 plant in the 5 to 20 ton range is hunting, starving or flooding back, or when an existing Type H valve needs replacing and the flanges in the line can be reused.
