The GBW21 variant provides two adjustable switching points within a gauge range of 13 to 425 psi, allowing precise turn-on\/turn-off control for mid-range pressures. It uses a 1\/4 in NPTF process connection and a 1\/2 in conduit entrance, facilitating typical installation in control panels or near pressure lines. Built for rugged industrial environments, this switch combines dependable mechanical operation with straightforward field adjustment to match your system's pressure requirements. The 9012GBW21 is a Square D product under Schneider Electric's Industrial Controls line, designed to deliver repeatable performance in applications such as water pumps, irrigation systems, and light-duty hydraulic or pneumatic circuits where reliable on\/off pressure sensing is essential.\u003c\/p\u003e\u003c\/div\u003e","brand":"Square","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46253911965930,"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-011.png?v=1788727428","url":"https:\/\/gtghardware.com\/products\/schneider-electric-9012gbw-21-pressure-switch","provider":"GTG Hardware","version":"1.0","type":"link"}
