PRODUCT DESCRIPTION
Tecofi RC4240 Cast Iron Balancing Valve
RC4240 is a Tecofi (France) ductile iron flanged PN16 balancing valve with a variable orifice, a handwheel with opening indicator and stroke limiter, from DN65 to DN600. This page covers RC4240 only; RC4241 is the fixed-orifice type with a calibrated orifice plate on the inlet flange (PN16), and RC4251 is also a fixed-orifice type but flanged PN25.

Kvs and weights are as printed in the datasheet dimension table; the datasheet gives no weight for DN600. Ref codes follow the pattern RC4240-xxxx where xxxx is the DN (for example RC4240-0100).
Difference from RC4241 and RC4251
- Orifice: RC4240 has a variable orifice adjusted by a handwheel with opening indicator; RC4241 and RC4251 have a calibrated orifice plate on the inlet flange for fixed flow measurement, with a flow measurement accuracy of ±5% at any open position per BS 7350 (RC4241 / RC4251 datasheets).
- Pressure rating: RC4240 and RC4241 are PN16 (maximum pressure 16 bar); RC4251 is PN25 (25 bar).
- Kvs: the RC4240 dimension table has its own Kvs (for example DN65: 83.8; DN100: 178.7), different from RC4241 / RC4251 (DN65: 104; DN100: 213).
- Materials, temperature (-10°C / +120°C), face to face, L / D / H dimensions and RAL 6005 epoxy coating are the same for all three codes in the datasheets.
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 PN16; face to face to EN 558-1; pressure tests to EN 12266-1, DIN 3230, BS 6755 and ISO 5208 (body 24 bar, seat 17.6 bar). The datasheet has a “Product approvals” heading but lists no specific approval.

FAQ
Frequently asked questions about RC4240
How does RC4240 differ from RC4241 and RC4251?
RC4240 is a variable orifice adjusted by a handwheel with opening indicator; RC4241 and RC4251 are fixed-orifice types with a calibrated orifice plate on the inlet flange. RC4251 differs from RC4241 in being PN25 instead of PN16.
What size range and pressure does RC4240 cover?
DN65 to DN600, flanged to EN 1092-2 PN16, maximum working pressure 16 bar, temperature -10°C to +120°C.
How is flow adjusted on RC4240?
RC4240 is operated by handwheel, with an opening indicator and stroke limiter, and the adjustment positions can be locked (per the datasheet).
What media is RC4240 used with?
The datasheet gives heating circuits and air conditioning, with heat transfer fluids (water, glycol water...), refrigerant, etc.
What is needed for a quote on RC4240?
Send the code, DN, PN rating, medium and working temperature, the flow to be balanced and the quantity. CAD replies with a quote within 24 working hours.
