MODEL SJ-530 THREE PORT BALL VALVE
The Shurjoint Model SJ-530 is a grooved-end three-port ball valve designed to divert media from bottom inlet to either of the two outlets ports. The valve port is a regular port size and the stem is a blowout proof design to MSS SP-72 and API Standard 608. The valve is supplied with a carbon steel lever handle equipped with a tamper resistant locking device.
The valve body is made of ferritic ductile iron conforming to ASTM A395/A (UNS F33100) with black electro deposition coating. The three-port ball is austenitic stainless steel to ASTM A351 CF8M (316) and blowout proof stem is stainless steel to ASTM A479 Type 316. All materials are chosen to meet the requirements of NACE MR0175-2003.
* Working pressure is based on connection with roll- or cut-grooved standard wall carbon steel pipe.
‡ For the first opening or closing of the valve when the valve is not continuously operated, an additional torque of 2.0 – 2.5 times the listed operating torque is normally required.
