1 - Technical data• Range:
- DN 50 to 1000 for XGS design.- DN 50 to 800 for XG design.- DN 50 to 300 for XGA design
• PN 10, 16 or 25 (depending on functions).• Maximum temperature: +1°C to +65°C.• Seating: class A according to standard ISO 5208-2.• XG and XGS designs:
- Face-to-face dimensions according to standards EN 558-1 series 1 (except DN 1000) and ISO 5752 series 1 (except DN 1000).
• XGA design:- Face-to-face dimensions according to standard ISO 5752 series 8
(except DN 300).• Flange drilling according to standards EN 1092-2 and ISO 7005-2: ISO PN10,
16 or 25 for DN 50 to 1000 (other drillings on request).• Fluid: drinking water or 2 mm filtered untraited water.
2 - Characteristics and performances• How to choose the design:
- Bayard range offers two different versions: XG and XGS design.- The decision which design to take depends on the required application
and on the pressure and flow rate conditions.- The XGS design specially fits for a pressure reducing application and
when there is a risk of cavitation.- The XG design suits better for low head loss conditions.
Mechanical resistance: - Main valve PN25 in standard version (PN40, please consult us).- Pilot circuit PN10, PN16 or 25 according to the expected applications.
(Other possibilities please consult us).
Control accuracy:Control accuracy is guaranteed by:
- The pilot system principle.- The linearity between the open section freed by the movements of the
mobile unit and its stroke.
In the mentioned operating range, the accuracy for pressure control is more or less 5% (other functions: see dedicated data sheet.)

Hydrobloc control valve
• Head loss curves for fully open valve
Curves and data established for water at 20°C for standard valve mounted on horizontal pipe. Kv: (flow rate factor) is the flow rate at 20°C expressed in m3/h which generates a head loss of 1 bar inside the valve.
3 - Hydraulic characteristics
Hydrobloc control valve
• How to choose the diameter
The diameter of the valve must be chosen according to the flow rate conditions and the pressure on the valves. Generally two cases are to be considered:
Case 1: The head loss of the valve has to be as low as possible (2 to 5 according to the DN and design) because the availa-ble head loss or the static pressure are ≤ 1 bar.
Case 2: The available head loss is high, so higher velocities can be admitted (beforehand, check that the available head loss is higher than the head loss through the fully open valve at the maximum considered flow rate).
