The Spirax Sarco M10V is a three-piece industrial fluid isolation ball valve. It is intended for manual pipeline shutoff and isolation only and must not be used as a control valve. Available in full-bore and reduced-bore configurations, it supports threaded, butt-weld, socket-weld, and flanged connections. The body is available in galvanized carbon steel or F316L stainless steel, with a maximum allowable pressure of 70 bar g. It is suitable for isolation during maintenance of saturated steam lines and equipment branches, as well as industrial gas lines where antistatic performance is required.

Application scenarios
Saturated Steam Line Isolation
For manual shut-off and isolation in industrial saturated steam lines and equipment branches, enabling maintenance of pipe sections or equipment. The M10V is designed as an isolation valve, and product documentation specifies a maximum operating pressure for saturated steam of 10 bar g (184°C).
Antistatic Isolation in Industrial Gas Lines
For industrial gas lines requiring reliable shut-off and isolation with antistatic protection. The M10V is an industrial fluid isolation valve and complies with the antistatic standards ISO 7121 and BS 5351.
Selection points
Leakage Class and Antistatic Standard
Leakage testing complies with ISO 5208 Class A and EN 12266-1 Class A; the antistatic design complies with ISO 7121 and BS 5351.
Full-Bore and Reduced-Bore Configurations
The M10V is available in full-bore and reduced-bore configurations. Select the appropriate configuration according to the required flow capacity of the pipeline.
Valve Body and Bonnet Material Grades
The M10V2 has a galvanized ASTM A105 carbon steel body and bonnet. The M10V3 and M10V4 have ASTM A182 F316L stainless steel bodies and bonnets.
Installation & maintenance notes
For Isolation Only
The M10V is for fluid isolation only and should be used fully open or fully closed. It must not be used as a control valve for throttling.
FAQ
How does the M10V three-piece ball valve work, and what is it used for?
The M10V is a three-piece ball valve for isolating industrial fluids and is not suitable for use as a control valve. Its three-piece construction allows quick maintenance without dismantling the pipeline. It is available with a range of threaded, welded, and flanged connections.
Which bore sizes and connection types are available?
The valve is available in full-bore and reduced-bore configurations. Connection types include threaded BSP, BSPT, and API/NPT connections, BW butt-weld, SW socket-weld, and flanged connections. Flange ratings include ASME ANSI Class 150/300 and EN 1092 PN40, with sizes from 1/4" to 2-1/2".
What certificates and compliance information are available?
An EN 10204 3.1 certificate is available. The product complies with the European Pressure Equipment Directive 97/23/EC. Confirm the requirement for CE marking when placing the order.
How should the material and construction options be interpreted when selecting a valve?
Valve body materials vary by model: the M10V2 has a galvanized carbon steel body, the M10V3 has a stainless steel body, and the M10V4 is all stainless steel. The seat is PTFE. Confirm the specific configuration against the model and application conditions.
Which parameters and details should be reconfirmed on site or when ordering?
Confirm the maximum operating pressure, minimum operating temperature, differential pressure limits, and certificate requirements at the time of ordering, based on the specific model and flange standard. For a specific area or operating condition, contact the supplier to confirm the correct configuration.
