The rugged Gulfproofed anodized cast-aluminum body houses steel and aluminum internals, Viton valve seats and seals, a Viton or Buna N diaphragm, and a stainless steel piston, designed for reliable service in demanding environments. Sensing lines connect via 1\/4\" O.D. tubing, and port A can see up to 80 psi (5.5 bar); the unit weighs about 5.5 lb (2.5 kg) and mounts on the back with two 3\/8\"-16 tapped holes, with the vent typically at the bottom. When the differential is reached, pressure entering port A is vented to port B, enabling applications such as gas-compressor safety shutdowns or monitoring differential pressure across a filter to indicate clogging.\u003c\/p\u003e\u003c\/div\u003e","brand":"AMOT","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51659938890030,"sku":null,"price":73.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_4cafb3b6-31d5-4dde-975b-c936d7a6cd74.jpg?v=1769531011","url":"https:\/\/plgautomation.com\/products\/industrial-4064b21a-pressure-sensing-valve-1-4in","provider":"PLG Automation ","version":"1.0","type":"link"}
