DELCO S10 / A28W Stainless Steel Threaded Safety Valve, Male Inlet, Spring Loaded

✅Compact Threaded Design: Features a space-saving body with a standard Male NPT/BSP Inlet and Female Outlet, allowing for direct installation onto pressure vessels or piping tees without bulky flanges.

✅Stainless Steel Construction: All wetted parts are machined from SS304 or SS316, providing superior resistance to rust and chemical attack compared to brass or bronze valves, suitable for food, pharma, and chemical industries.

✅Adjustable Set Pressure: Equipped with an internal adjusting screw protected by a top cap, allowing technicians to precisely calibrate the Opening Pressure (Set Pressure) within a specific spring range to match system requirements.

✅Manual Testing Lever (Optional): Available with a Lifting Lever (Type A28W) that enables periodic manual discharge testing to ensure the valve seal is not stuck, a critical safety feature for steam and air receivers.

✅Leak-Tight Sealing: Utilizes a precision-lapped metal seat or soft seal (PTFE/Viton) to ensure bubble-tight shutoff up to 90% of the set pressure, preventing wasteful leakage of expensive process fluids or gases.
