Cardinal Valves

Features and Options:​

• Cardinal valves are robust in design so that over tightening or minor abuse encountered in handling, or during factory/field installation will not result in malfunctioning of the valve

• All parts are made from non-corrosive or suitably protected material to withstand outdoor exposure on external surfaces and hot transformer oil on internal surfaces

• Fasteners are designed to prevent loosening under normal operating conditions

• In the open position, the valve flapper will not vibrate or flutter when valve is installed close to the suction side of the pump, flapper acts as a fluid straightener, thus enhancing the pump's performance

• Valve design temperatures are –40°C (–40°F) to 100°C (212°F)

• Operating handle displays the valve's open and shut position and is designed so it can be manually locked in either position

• Valves are individually coated with oil and sealed to protect from contaminants
