This safety shut-off valve is a reliable refrigeration valve used to control the flow within the pipelines of refrigeration or HVAC systems. Using our advanced designs and manufacturing techniques, we provide several models of this industrial valve, but all our shut off valves include the following features:
1) Made with quality materials in compliance with industry standards;
2) Equipped with a valve slap and valve seat that are sealed by Iron base alloys or Stellite cobalt-based alloys. This valve is highly resistant to wear, high heat, corrosion and abrasion, making it long lasting and durable;
3) The valve stem has gone through quenching and surface nitriding treatments so it won't get scratched up easily;
4) Different flanges and several types of sealing surfaces are available;
5) Customers can choose the material of the valve body, packing, and gaskets. We provide valves based on the working conditions of our customers' applications;
6) This valve uses a back seal which allows users to change the direction without shutting down the equipment.
