The actuator uses stainless steel hardware and offers a maximum deadband of 0.3 psig (0.02 bar), while the valve trim is stainless steel (316) with replaceable threaded seats for easy maintenance. The packing is spring-loaded Teflon V-rings by default, with optional graphite or high-temperature packing available. Seat leakage conforms to ANSI\/ISA 70-2 Class IV for metal seats and Class VI for PTFE soft seats. End connections for Type J valves cover ½ to 2 in sizes and can be threaded or flanged depending on configuration. Type J can be configured for air-to-close or air-to-open operation and is suitable for steam, water, gas and general process service, providing a flow-to-open control characteristic with broad flow capacity.\u003c\/p\u003e\u003c\/div\u003e","brand":"Spence","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46259679265002,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-014.png?v=1788727428","url":"https:\/\/gtghardware.com\/products\/spence-j3kg613-pneumatic-diaphragm-globe-control-valve","provider":"GTG Hardware","version":"1.0","type":"link"}
