• Zero leakage • Protected o-ring • Full flow passages • Freedom from wire drawing • Panel mount standard • Hand wheel or toggle handle Technical Data Body Construction Material 316 or 303 stainless steel Stem Materials 316, 303 or 17-4 PH stainless steel Gland Nut Materials Brass or 17-4 PH stainless steel O-ring Materials Buna N, Neoprene or Viton® Spring Material 302 stainless steel Handle Materials • Handle wheel: die-cast zinc, color blue • Toggle: forged steel, cadmium-plated Leakage • Internal: zero • External: zero Based on o-ring material, see “How to Order”. Actuating Force Handle Secured with jam nut for easy removal and replacement when valve is panel mounted. No flow for approximately 1½-turns of handle, then approximately 4½-turns from full closed to full open. Gland nut requires no adjustment. O-rings provide leak-proof seal. Stainless steel stem provides corrosion and wear resistance. Stem threads are completely removed from flow path to permit “lifetime” lubrication and to avoid contamination of fluid. Panel mount is standard. Spacer limits stem travel so that it bottoms on a non-critical stop. No matter how tightly the handle is wrenched, the seat cannot be damaged. Teflon® spiral back-up rings are virtually frictionless which protects o-ring seal from wear and tear. O-ring seal provides positive, leak-tight shutoff. Floating sleeve protects o-ring from extrusion and cutting action of liquid flow.
