Δ. Technical parameters

Item	Parameters	Remarks
Shell liquid test pressure	35~135MPa	No leakage under the pressure in 3 minutes
Seal liquid test pressure	35~135MPa	No leakage under the pressure in 3 minutes
Gas test pressure	0.6MPa	No leakage under the pressure in 3 minutes
Suitable temperature	-50℃~200℃	according to material properties
Suitable medium	liquid or gas

Δ. Application:

The grease fittings can be installed at the sealing parts of the valve seat and stem. The sealing grease can be injected by the grease filling valve to play the role of a temporary seal when the sealing parts begin to leak due to wear or other causes, in order to take timely remedial measures.

Δ. Note:

1. surface treatment: Fe/Ep\Zn8.

2. the other requirements of customers could be satisfied, including material, material specification, outside size, length, connecting thread, surface treatment, etc.

3. product surface was identified according to the actual material.

4. the working pressure should be 1.2 times more than the testing one when we make the choice. exchange method:1psi=6.895kpa=0.006895Mpa,for example,5000psi=5000×0.006895*1.25≥43Mpa
