Operating Instructions	N/A Valve is operated by turning the bleed port nut with a wrench. Use appropriate back-up wrench to hold body, while turning bleed nut. As the bleed nut is turned, pressure forces the ball off the seat. Pressure is vented through a hole drilled in the nut, angled back toward the body of the valve. Make sure flow is directed away from user. Those using the valves should wear protective clothing, especially goggles. No attempt should be made to repair or dismantle the valve.
