Designed to meet the requirements of the most severe industrial applications, IPEX is pleased to introduce the VKR Dual Block® Regulating Ball Valve. The new VKR combines the reliability and safety features of the IPEX VKD ball valve with a newly designed profiled ball. The patented ball design provides linear flow regulation throughout its full range of operation even when the valve is open just a few degrees. Like a traditional shut-off ball valve, the VKR has a 90° operating angle which allows the use of a standard quarter-turn actuator, ensuring perfect alignment and reducing the torque required for actuation. The patented Dual Block® mechanism locks the union nuts in place preventing back-off during severe service conditions.
VKR Regulating Ball Valves are part of our complete system of IPEX pipe, valves and fittings, engineered and manufactured to our strict quality, performance and dimensional standards.
