Large zero point
deviation

• Orifice contaminated

Remove valve and have it repaired

External leakage

Seal defective
• Seal at the connection

surface is defective

Remove the valve and replace the seals

• Seal at filter screw is

defective

Disassemble the filter screw and replace
the seal

• Other leakage
