The Betts SV904SSM is a manual sliding gate valve, designed primarily for use in tank trailer bottom outlets, such as those in petroleum, chemical, and dry bulk transport applications. It functions as an economical external stop valve with metal-to-metal seating, providing quick open/close operation for reliable flow control in low-pressure environments. Key Features: ✅ Operation: Manual handwheel actuation for smooth, low-torque quick opening and closing; adjustable packing nut with woven PTFE-infused packing for easy stem adjustments and leak prevention. ✅ Design: 316 stainless steel construction for the body, stem, and gate/discs, offering premium corrosion resistance; compact and durable for demanding industrial use. ✅ Safety Integration: Metal-to-metal seal provides bubble-tight shutoff and advantages in abrasive or high-viscosity media, though susceptible to wear—ideal for applications not requiring maintainable O-ring seats. ✅ Specifications: Valve Type: Sliding gate valve with metal-to-metal seat (manual action). Size: 4-inch nominal diameter. Connections: 4-inch TTMA flange x 4-inch TTMA flange (8-bolt). Material: 316 stainless steel body, stem, and gate. Pressure Ratings: Maximum working pressure 50 PSI; burst pressure 200 PSI. Temperature Range: -40°F to 500°F. Compliance: Meets TTMA standards; California Proposition 65 warning for potential exposure to chemicals like lead and chromium.
