PRUSS and OMB Introduce PROcv Control Valve Series for Global Industrial Applications

PRUSS GmbH and OMB Valves Group have jointly launched the new PROcv range of control valves, developed to deliver high-performance flow control solutions for power generation, oil and gas, chemical processing and other industrial applications worldwide. The newly introduced PROcv series combines PRUSS’ engineering expertise in customized control valve design with OMB’s large-scale industrial manufacturing capabilities. The collaboration aims to offer customers a standardized yet highly efficient control valve platform that balances performance, availability and cost-effectiveness.
The low-pressure PROcv range includes straight globe control valves manufactured in accordance with ASME B16.34 standards. The valves are available in sizes ranging from 1 inch to 12 inches and are offered in WCC and CF8M material grades with pressure classes of 150, 300, 600 and 900. The design has been developed to support a broad range of industrial operating conditions while maintaining reliability and ease of maintenance.
The series incorporates a cage-style, single-stage trim system with a replaceable seat based on a plug-in configuration. The valves support both linear and equal-percentage flow characteristics and are available with leakage classes IV and V using metallic seat sealing arrangements. For valve sizes above 4 inches, the design utilizes a balanced trim configuration equipped with metallic piston rings to improve operational stability and flow performance under higher process loads.
The PROcv range also features a graphite gasket system suitable for operating temperatures from –20°C to 450°C, enabling use across a wide range of industrial process environments. According to the companies, the valves have been engineered around a standardized platform architecture that simplifies manufacturing and improves product availability.
The design strategy uses one standardized maximum seat diameter per body size along with common internal components across all pressure classes. Three standardized Cv values are available for each nominal pipe size and flow characteristic, with flow adjustments achieved through drilling patterns applied at the maximum seat diameter. This level of standardization is expected to support shorter lead times, simplified maintenance and optimized inventory management.
Engineering development for the PROcv series was carried out by PRUSS in Hannover, while manufacturing operations are being handled at OMB’s production facilities in Bergamo, Italy. The companies stated that the partnership enables the integration of specialized engineering design with scalable industrial production processes.
The valves can be supplied with PRUSS PPA pneumatic diaphragm actuators or electric multi-turn actuators featuring drive output form A with integrated thread nut systems. The configuration options are intended to support flexible installation requirements across multiple industrial sectors. Company representatives stated that the high degree of standardization within the PROcv platform is expected to improve delivery timelines while maintaining the engineering quality and operational reliability demanded by industrial customers worldwide.
