Description

Fisher Yarway 25 VenTemp Desuperheater
The Fisher Yarway 25 VenTemp Desuperheater is designed for low-capacity superheated steam systems where the load is fairly constant, providing a simple and cost-conscious solution for effective steam temperature control.
Key Features
•Forged construction for robust service
•Low pressure loss across the desuperheater station
•Works with water pressure only marginally above steam pressure
•Venturi nozzle type design
•Wide range of Cv (Kv) capacities available
•Connection & rating options: ASME B16.5 Class 150–2500, EN 1092-1 PN 25–400, BW to ASME B16.25 / DIN 2559

Selection Guide (What we need to quote the right build)
To avoid back-and-forth, send any of the below you already have:
•Steam line size (NPS/DN) + connection standard (ASME/EN)
•Steam pressure / temperature (inlet & target outlet)
•Steam flow (normal / max / min)
•Spray water source: pressure available (confirm marginally above steam pressure is feasible)
•Material preference: CS / SS / Alloy
•Any site requirement: noise / erosion / turndown / control philosophy
Applications
•Steam conditioning in low-capacity superheated steam systems with stable loads
•Desuperheating stations where low pressure drop is important
Project Support
•Model selection support (Cv/Kv range, connection/rating match)
•Cross-check against site specs (materials, standards, station ΔP)
•Documentation support: datasheet / drawing / lead time confirmation (on request)

FAQ
Q1: Is this OEM / genuine?
A: We supply genuine Fisher / Yarway items with proper identification and documentation (on request).
Q2: Can you help match pressure class & connections?
A: Yes—options include ASME B16.5 Class 150–2500 and EN PN 25–400 (plus BW standards).
Q3: Why VenTemp nozzle type?
A: The Venturi nozzle type supports effective cooling with low pressure loss in the station.
