Cast Iron Threaded Ball Check Valve
Ball Check Valve
The ball check valve is mainly used in wastewater applications, power plants and process industry. The ball check valve is suitable for use in polluted media as the ball shaped valve prevents the buildup of dirt. Typically a wastewater lift station will have a ball check valve to prevent reverse flow. This is why sometimes these valves are called non-return valves. A ball check valves operate best with 3-5 feet per second velocity and 20 feet of head pressure.
Design
Junya's threaded ball check valve was designed according to BSP/BSP (we can also manufacture products according to other standards/specifications according to the requirements of clients). The epoxy-coated body is made from ductile iron.
The ball check valve has an NBR vulcanized iron ball. The ball is easily removed for maintenance through the ductile iron cover. This cover is sealed off by an NBR O-ring.
The bolts, nuts and washers are provided in AISI 304 stainless steel as standard.
