BALL VALVE TYPE 21[1/2-4inch]（15-100mm）
Easy to Be Automated (No Madification required)
Featuring a new intregal molded top flange. The BALL VALVE TYPE 21 can easily be converted from the manual to automatic without replacing the body.
Simple Installation on Panel Piping
New bottom stand with an insert hole allows the valve to be secured on bench or panel only by inserting a metallic insert.
The stem uses a double-O-ring, sealing arrangement improving durability sealing performance. The upper O-ring groove is deeper than the lower O-ring groove. Because of this design, the stem would break first at the upper O-ring groove, acting as a back up seal.
Multi Functional Handle
Removing the handle and placing the raised lugs into the carrier allow for easy disassembly of the valve. *The handle has another color.(blue, white, yellow)
