PRODUCT DESCRIPTION
Tecofi RC4251 Cast Iron Balancing Valve
RC4251 is a Tecofi (France) ductile iron flanged PN25 balancing valve with a fixed orifice (calibrated orifice plate on the inlet flange), maximum working pressure 25 bar, from DN65 to DN600. This page covers RC4251 only; RC4241 is the same fixed-orifice type but PN16, and RC4240 is the variable-orifice type, PN16.

Kvs and weights are as printed in the datasheet dimension table; the datasheet gives no weight for DN600. Ref codes follow the pattern RC4251-xxxx where xxxx is the DN (for example RC4251-0100).
Difference from RC4240 and RC4241
- Pressure rating: RC4251 is PN25 (max. 25 bar, flanges to EN 1092-2 PN25, body test 37.5 bar, seat test 27.5 bar); RC4241 is PN16 (max. 16 bar, body test 24 bar, seat test 17.6 bar).
- Orifice: RC4251 and RC4241 have a calibrated orifice plate on the inlet flange for fixed flow measurement, ±5% accuracy at any open position per BS 7350; RC4240 is a variable orifice adjusted by handwheel.
- Kvs, L / D / H dimensions, weights, materials and temperature (-10°C / +120°C) of RC4251 are the same as RC4241 in the datasheets; Kvs differs from RC4240.
Applications
Adjusts the flow rate in circuits by creating additional pressure loss through precise adjustment. Areas of use: heating circuits, air conditioning. Fluids: heat transfer fluids (water, glycol water…), refrigerant, etc. (per the datasheet).
Standards / Certifications
Designed to BS 7350:1990; flanged connection to EN 1092-2 ISO PN25; face to face to EN 558-1; pressure tests to EN 12266-1, DIN 3230, BS 6755 and ISO 5208 (body 37.5 bar, seat 27.5 bar). The datasheet has a “Product approvals” heading but lists no specific approval.
