It operates without electricity or compressed air, using a liquid-filled brass sensor, a 2m copper capillary tube, and a brass actuator to respond directly to process temperature changes. The set point is adjusted via a polypropylene knob located at the valve, covering a range of 40°C to 170°C. Constructed to comply with the EU Pressure Equipment Directive and UK Pressure Equipment (Safety) Regulations, and manufactured under Spirax Sarco's ISO 9001 quality management system, the SA122 is suited to Group 2 fluids including steam, water, and compressed air. Approximate weight is 2.3 kg, excluding the optional stainless steel thermowell.\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\u003cp\u003e\u003cb\u003eApplications:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eSteam-heated process systems\u003c\/li\u003e\n\u003cli\u003eHeat exchangers\u003c\/li\u003e\n\u003cli\u003eHot water generation and storage\u003c\/li\u003e\n\u003cli\u003eHVAC and building heating systems\u003c\/li\u003e\n\u003cli\u003eFood and beverage processing\u003c\/li\u003e\n\u003cli\u003ePharmaceutical manufacturing\u003c\/li\u003e\n\u003cli\u003eChemical and general industrial process plants\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\u003cp\u003e\u003cb\u003eSummary:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eSelf-acting control — no electricity or compressed air required\u003c\/li\u003e\n\u003cli\u003eTemperature range: 40°C to 170°C\u003c\/li\u003e\n\u003cli\u003e2m copper capillary tube with PVC-coated armoured covering\u003c\/li\u003e\n\u003cli\u003eKnob adjustment at the valve for simple set point changes\u003c\/li\u003e\n\u003cli\u003eBrass sensor and actuator; steel mounting bracket\u003c\/li\u003e\n\u003cli\u003eCompliant with EU PED and UK Pressure Equipment (Safety) Regulations\u003c\/li\u003e\n\u003cli\u003eManufactured under ISO 9001 quality management system\u003c\/li\u003e\n\u003cli\u003eSuitable for Group 2 fluids including steam, water, and compressed air\u003c\/li\u003e\n\u003cli\u003eApproximate weight: 2.3 kg (excluding thermowell)\u003c\/li\u003e\n\u003cli\u003eOptional stainless steel thermowell available\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Flocon","offers":[{"title":"2m","offer_id":58523029963136,"sku":"40.3811190","price":1144.5,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0524\/4531\/5228\/files\/Spirax_20Sarco_20SA121_20Self-Acting_20Temperature_20Control_20System.jpg?v=1784858831","url":"https:\/\/www.flocon.co.uk\/products\/spirax-sarco-sa122-self-acting-temperature-control-system","provider":"Flocon Valves Pipes \u0026 Fittings","version":"1.0","type":"link"}
