Operation & Maintenance Manual

1. The Face to Face conforms to EN558 or ANSI B16.10, and the flange conforms to EN1092-2, B16.5 Please check the standards during installation.
2. It can be installed on horizontal or vertical pipelines.
3. The installation position should ensure to be used, maintenance and replaced easily.
4. Two-way use is allowed (the direction of the pipeline fluid can be ignored during installation).
5. Before installation, the valve should be stored in a dry place indoors and the wedge is in the open position.
6. The following work should be prepared before the valve is installed:
6.1 Carefully check the conditions of use before installation to confirm that it is consistent with the performance specifications of the valve.
6.2 Clean the inside of valve and sealing surface, and no any dirt on it.
6.3 Check the transmission device to see if it is firmly connected to the flange.
7. After the valve is installed, it should be inspected regularly. The main inspection items are as follows:
7.1 Check whether the valve body and bonnet are well sealed.
7.2 Check whether the seal between the bonnet and the compression cap is good.
7.3 Check whether the seal between the valve stem and the compression cap is good.
7.4 Check whether the seal between the valve body and the wedge is good.
7.5 Check whether the valve rotation is flexible.
7.6 After the valve is assembled, there must be no jamming when the switch rotates.
7.7 After the valve is assembled, the sealing and shell test should be carried out as required.
8. Possible faults,reasons and solutions:
Possible Faults Reasons Solutions
Wedge sealing surface leaks The rubber of wedge is damaged Replace the new wedge
The leak between stem and gland O-ring is damaged in the gland Replace the new O-ring
The leak between bonnet and gland The O-ring outside the gland is damaged or the gland bolt is loose Replace the O-ring or tighten the gland bolt
The leak between bonnet and valve body O-ring is damaged in the bonnet Replace the new O-ring

Specific requirements for casting defect inspection

This specification clarifies the specific requirements for casting defect inspection and is applicable to the inspection of castings of this company and outsourced companies.
1. The casting surface must be clear and correct, and there must be no wrong characters, missing characters, or unclear characters.
2. There must be no single sand holes or pores on the casting surface that exceed 1MM, and shallow but piece-by-piece casting defects. Sand holes and pores on the casting surface that are less than 2MM can be repaired and smoothed with putty if they are not on the sealing surface and do not affect the wall thickness.
3. The flash, burrs, and box seams on the casting surface must be polished and smooth.
4. The casting must not have obvious defects such as deformation, shrinkage, lack of meat, box expansion, and box misalignment. For the gate frame, its thickness dimension must be inspected with the corresponding inspection fixture; for the large cover of the check valve, the plane with the O-ring groove must be inspected with a flatness inspection fixture.
5. The asymmetry between the inner cavity and the outer shape of the casting shall not exceed 1.5MM (including the center and flange).
6. The inner cavity of the casting shall not have defects such as bulging, lack of meat, excess meat, burrs, etc., and its shape and size shall be inspected with the corresponding gate.
The gate used (DN40-200) shall be replaced every six months, and DN250-600 shall be replaced once a year.
7. The surface roughness of the casting shall refer to the roughness sample: ≤N11~12, see Appendix 1.
8. The surface cleanliness shall be visually evaluated according to ISO8501-Sa2.5, see Appendix 2.
9. Each casting that passes the inspection shall be marked with its own inspection mark.
10. The castings inspected every day shall fill in the "Casting Inspection Record" truthfully.
11. Each furnace of the outsourced casting shall be accompanied by a test block, which shall be brought with the goods. If there is no test block, the goods shall not be accepted.
12. This specification is applicable to both our factory and outsourced manufacturers.
All casting outsourcing manufacturers are required to conduct 100% self-inspection according to the above inspection items, and then the factory inspection personnel will randomly inspect 20% of the castings sent in. If unqualified items are found, the specification will be fully inspected or rejected, and the relevant manufacturer will re-inspect and sort out the project, and after completion, it will be submitted to the inspection personnel for re-inspection.
