  • products details
YFL cryogenic gate valves are done with low temperature treatment from semi-finished mechanical parts to final finished whole valves to make sure the materials can meet the cryogenic working conditions and ensure the excellent sealing performance to avoid leakage of inflammable and explosive medium like LNG and LPG. 

YFL cryogenic gate valves features:

1. Extended stem protects the stem packing to make sure the stem sealing performance

2. Extended stem made from advanced Nitronic 50 with high tensile and low friction under extreme low temperature

3. Body and bonnet in material of Austenitic stainless steel with excellent impact strength, minimal heat loss and strong corrosion resistance

4. Sealing face overlaid with stellite 6 and PCTFE or PTFE as soft insert when extremely tight shutoff needed

5. Packing in material of PTFE and graphite as secondary packing when fire safe needed

6. All valves are degreased, cleaned and sealed completely to avoid contamination
