Made of dielectric Zenex thermoplastic to withstand chemicals, these gate valve devices have an outward/inward rotation that surrounds the valve-operating handle to protect against accidental valve opening. Plus each size rotates into itself and nests into the next larger size to save space, while its center knockout can be removed for rising stem gate valves. Lockouts perform effectively in extreme conditions (-50°F to 350°F), too, and include hi-vis permanent safety labels in English, French, and Spanish.
