The valve should not experience loads from the pipeline (bending, compression, stretching, torsion, distortions, vibration, misalignment of pipes, uneven tightening of fasteners). If necessary, supports or expansion joints should be provided to reduce the load on the valve from the pipeline. The valve has no direction of flow. Can be installed in any position, but in a visible, accessible place to ensure their complete and easy opening / closing. Sealing of coupling joints should be carried out using sealing materials: fum, sanitary flax, anaerobic sealant, sanitary thread. Excessive sealing material and excessive tightening torques can damage the valve and fitting. Before installing the valves, the pipeline must be free of scale and rust. At the end of their installation, heating and water supply systems must be flushed with water until it comes out without mechanical suspensions (SNiP 03.05.01). The valve must be securely fixed to the pipeline; leakage of the working fluid along the threaded part is not allowed. According to clause 4.1 of SNiP 3.05.01-85 `Internal sanitary systems` after installation, a gauge test of the system`s tightness must be carried out and drawn up in accordance with Appendix No. 3 to SNiPu. This test allows you to protect against leaks and damage associated with them.
