BUTTERFLY VALVE

Specification(Wafer, Full Lug, Double Flange) Standard accroding to ISO05752 - BS5155 - MSS SP67 - API 609 Product range 40mm up to 1000mm(1.1/2"~40") Pressure range designed for maximum working proessure of 16bar(240psi) Flange connections The shape of valve body has been so designed as to allow flange bolt alignment onto following standards. Wafer type valve has been successfully developed to fit multi functional application onto either connection standard in the same configuration, mainly. ISO PN6, 10, 16, 20 MSS SP 44 CL. 150 ANSI B16.1 CL. ANSI B16.5 CL. 150 BS4504 PN6, PN10, PN16 BS10 Table d and E AS2129 Table D and E JIS B2210 5K, 10K, 16K and 20K Face to face dimensions in accordance with ISO 5752, BS5155, MSS SP67 and API609 Actuator connection valves can be fitted with any 1/4 turn actuator equipped with a mounting plate meeting the standard ISO5211 Test Inspection Our valve are guaranteed to seal perfectly ( no visible leakage) in both flow directions, The test conforms to API598 * Body test : 1.5times the maximum working pressure with water. The test is performed on the assembled valve with the disc in half open position. * Seat and shaft seal test : 1.1 times the maximum working pressure. The shaft seal test and inspection is conducted simultaneously with seat test.
