01

Check the complete valve model

Record the valve model and suffix, along with the valve body and coil nameplates. Compare the inlet and outlet, mounting arrangement, pilot configuration and coil voltage and AC/DC type against the documentation for the installed unit.

02

Match the diaphragm kit

Use the complete valve model to find the kit number in the manufacturer’s parts list. Compare the mounting holes, centre plate and bleed-hole layout with the drawing and the original part. Confirm whether the kit includes any required pilot diaphragm, spring or seal.

03

Measure the flange and sleeve

Record the manifold-side and blowpipe-side connections separately. For a flange or sleeve, provide the mating diameter, bolt pattern, sealing surface and applicable insertion depth. A photo of the installed assembly helps document access and orientation.

Specify both ends of the fitting

For a threaded fitting, specify the thread form, nominal size, pitch and sealing method on each end. For a sleeve or non-standard adapter, provide the mating dimensions, available length and material requirements. Review a dimensioned drawing before ordering.

05

Confirm what needs replacement

For weak pulses or continuous leakage, have maintenance staff locate the fault before ordering a kit or complete valve. Follow the equipment manual and site isolation and depressurization procedures before inspection. List the valve position, model, symptoms, connection dimensions and quantity for each item.
