Page 2: Safety Information
Determine the correct installation situation and direction of fluid flow. iv) 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. -
Page 3: Pressure Systems
Allow time for temperature to normalise after isolation to avoid danger of burns. 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. -

Page 7: Installation
Valves are available for use on sea water or brine applications. Please contact Spirax Sarco for further information. 2.2 Serial numbers All Type 58 control valves bear a serial number which is stamped on the nameplate and should be noted in all contacts with the manufacturer. DN50 and DN80 DN100 Fig. -
Page 8: General Arrangement
2.3 General arrangement The Type 58 Control Valve should be fitted in a vertical position with the Port O at the bottom. For ease of maintenance an isolating valve should be fitted in the line serving each port, although for clarity these are not shown on the recommended installation layouts. - Page 9 Type 58 Type 58 Type 58 control control control valve valve valve Fig. 4 Multi-boiler installation with separate Type 58 on each boiler Flow to system Main Duty and Standby Pumps Boiler Boiler Boiler Type 58 control valve Return from System Alternative Position for Pump Fig.

Page 10: Temperature Range
2.5 Temperature range The sensor (18) is available in a choice of temperature settings as shown in Table 1 opposite. Types A, B, C, D and E are the standard and type X is non-standard. In each case the temperature at which the valve commences to move is stamped on the bottom end of each sensor (18). - Page 11 Table 1 - temperature settings Type Port Z commences to open Full flow to Z 57°C 66°C 63°C 71°C 74°C 82°C 82°C 91°C 40°C 49°C Where an X sensor is fitted the letter X on the nameplate will be followed by the temperature setting and in all cases full movement of the valve, opening port Z and closing port X will occur at a temperature 8/9°C higher.

Page 13: Operation
3. Operation 3.1 Adjustment After the Type 58 Control Valve has been put into service and allowed to settle down, if it is found that it is controlling at a slightly different temperature to that required, it may be adjusted over a small range as follows: Using a 16 mm A/F spanner hold the adjustment nut (1) and slacken the lock nut (2). - Page 14 3.2 Fail safe device In the event of failure of the sensor (18) allowing a substantial rise in water temperature, a temperature sensitive fuse will come into operation at approximately 95°C mechanically putting the piston into the position where full flow will be through port Z. In this position the valve can be operated manually, see Section 3.3.
-
Page 15: Manual Operation
3.3 Manual operation If by failure of the sensor or for some other reason the fail safe device has operated releasing the temperature sensitive fuse as described in Section 3.2, it is now possible to manually operate the valve as follows: Using a 16 mm A/F spanner hold the adjustment nut (1) and slacken the lock nut (2). -
Page 16: Maintenance
4. Maintenance 4.1 Inspection At least once a year the working parts should be removed for inspection. This can be done without uncoupling the valve body (5) from the pipework as follows but the valve should be isolated or the system drained. Undo nuts (4) and remove cover (3) by levering up evenly with two screw drivers, using the slots provided. - Page 17 Check that piston (8) is seating on machined face on cover (3). If not, it is either due to dirt, which should be cleaned off, or the safety fuse (9) is no longer ‘set’. If the latter should be the case, repair or replace as detailed in Section 4.3. Without dismantling further, immerse the sensor (18) in water which is about 7°C hotter than the temperature stamped on its end and see that the piston (8) moves.
- Page 18 4.2 To replace sensor If the sensor (18) has to be replaced, proceed as follows after isolating the valve and/or draining the system: Undo lock nut (12) using a 42 mm A/F box spanner and unscrew sensor tube (14 a ‘C’ spanner in the slot provided if necessary.

- Page 20 4.3 To Re-set or replace fail safe device If safety fuse has operated for any reason it can be either re-set or replaced as follows: Isolate the valve and/or drain the system. Remove cover (3) complete with working parts as described in Section 4.1. Remove sensor (18) as described in Section 4.2.
- Page 21 As an alternative a replacement fail safe assembly consisting of rod (9) ‘O’ ring (19) and tube (13) can be purchased from Spirax Sarco Ltd. To re-assemble, fit rod (9) into cover (3) taking care to include spring (6) and checking that ‘O’...

Page 22: Available Spares
Always order spares by using the description given in the column headed 'Available spares' and state the size, type and temperature range of the valve. Example: 2 - Piston assemblies, for a Spirax Sarco DN100 Type 58 temperature control valve having a temperature range A. - Page 23 Hole for 'C' spanner Fig. 20 IM-P041-03 CH Issue 5...
