A \u7247\u5f0f\u6c23\u52d5\u8776\u95a5<\/strong> in 304 stainless steel (316 to order), sized \u00d812.7 to \u00d8101.6 mm (1\/2\u2033 to 4\u2033 tube OD). The valve body is clamped between two ferrules and the disc rotates 90\u00b0 to open or close. A pneumatic actuator sits on the top platform, bolted through four M6 or M8 holes.<\/p>\n

It is short, light and cheaper than a ball valve of the same size \u2014 and that is exactly what it is for. Face-to-face runs 66 to 82 mm across the whole range, so it drops into piping that has no room for a ball valve. Full dimensions are on the dimension sheet above.<\/p>\n

The PTFE Seat and Your Line Temperature<\/h2>\n

\u6b64\u95a5\u9580\u7684\u95a5\u5ea7\u662f PTFE<\/strong>, and it is the seat that sets the working temperature \u2014 the 304 stainless body will take far more heat than the seat will.<\/p>\n

Tell us the temperature of your line when you enquire \u2014 a heated jacket, a hot flush, a wash cycle \u2014 and we will confirm the seat suits it.<\/p>\n
