Product Description

Selection	Restrictions (spherical ink)	Restrictions (carbon steel/stainless steel)	Installation instructions
•Built-in stainless steel check valve (CV) •Enlarged vent hole (LV) •Borne pass needle (BVSW)	• Design pressure (PMA): 25bar • Maximum operating pressure (PMO): 21.8bar • Maximum operating temperature (TMO): 232°C	• Design pressure (PMA): 40bar • Maximum operating pressure (PMO): 21.8bar • Maximum operating temperature (TMO): 300°C	Keep the valve body vertical during installation to ensure the vertical up and down movement of the bucket. The inlet and outlet of the valve are level, and the steam trap is installed below the drainage point to maintain the water seal inside the valve.
