Determine the correct installation situation and direction of fluid flow. iii) Spirax Sarco products are not intended to withstand external stresses that may be induced by any system to which they are fitted. It is the responsibility of the installer to consider these stresses and take adequate precautions to minimise them.
1.9 Tools and consumables Before starting work ensure that you have suitable tools and/or consumables available. Use only genuine Spirax Sarco replacement parts. 1.10 Protective clothing Consider whether you and/or others in the vicinity require any protective clothing to protect against the hazards of, for example, chemicals, high/low temperature, radiation, noise, falling objects, and dangers to eyes and face.
Spirax Sarco ball valves for these applications are clearly marked to allow the valve to be correctly installed, such that, when closed, the hole is facing the steam source.
2.1 General description The M10S three-piece body ball valve has been designed for use as an isolating valve, not a control valve, and can be serviced without removal from the pipeline (screwed and welded versions only). It can be used with the majority of industrial fluids for services ranging from vacuum to the higher temperatures and pressures.
Flanged ASME (ANSI) 150. Note 1: On the 2" FB and 2½" RB a PTFE gasket is fitted between the body and cap. Note 2: The flange standard may restrict the maximum operating pressure. Please check with Spirax Sarco. Body design conditions...
3. Installation Note: Before actioning any installation observe the 'Safety information' in Section 1. Although the valve has great structural integrity, severe misalignment and/or the pulling effect of incorrect pipe length will have a detrimental effect on the valve and must be avoided. Particular attention should be paid to correct pipe alignment such that the inlet pipework and valve are all on the same axis.
4. Commissioning After installation or maintenance ensure that the system is fully functioning. Carry out tests on any alarms or protective devices. 5. Operation The valve is operated manually by a handle, or automatically by an actuator. Special care must be taken to ensure that the movement is made in the correct direction.
Always order spares by using the description given in the column headed 'Available spare' and state the size and type of ball valve required. Example: 1 - Seat and stem seal set for a Spirax Sarco ½" M10S2FB ball valve. Fig. 5 M10S screwed version shown...
