Control Ball Valves and Manual and Automated Valves

By Pibiviesse

We have a wide range of high-performing products, designed to withstand the toughest of service conditions. Our valves are all welded in sizes up to 64in, and are in a pressure class up to ANSI 2500 and API 15000.

Side Entry

Pibiviesse side entry ball valves are specified for transmission pipelines, pumping, offshore platforms, onshore terminals, pig traps, measuring stations, compression and re-injection units, as well as any critical applications, such as subsea installations, cryogenic service in LNG plants, high temperature and abrasive services.

These valves can be made in various grades of carbon steel, stainless steel and high alloys.

Top Entry

Pibiviesse top entry ball valves are specified for transmission pipelines, pumping, offshore platforms, onshore terminals, pig traps, as well as compression and re-injection units, measuring stations' critical applications, such as subsea installations, cryogenic service in LN Gplants, high temperature and abrasive services.

Our top entry valves are full inline field repairable, and can be used in any critical service applications where in-situ field reparability and quick turnaround are needed. Thanks to these characteristics, top entry valves can also be welded directly onto the pipeline, whilst still allowing for easy maintenance operation.

Top entry valves are sized to endure external loads from the pipeline even when the bonnet, ball and seats are removed for maintenance. The cast body and forged bonnet construction allow the use of various grades of carbon steel, stainless steel and other alloys.

Fully Welded Ball Valves

Pibiviesse fully welded ball valves are specified for transmission pipelines, pumping and compression units. These valves can be supplied in the configuration with bolted or welded bonnet. The fully welded body construction allows the use of forged materials in the various grades of carbon steel.

Control Valves

Pibiviesse's axial rotary control ball valves are developed with the proprietary CAGEBALL TM technology, in accordance to international standard ISA S75, IEC 534.

The ball has an integrated patented cage trim to eliminate, or minimise the hydro or aerodynamic flow control disturbances. The cage is designed to meet the project requirements with a number of attenuating plates to divide the pressure drop in stages and reduce the noise generated by the pressure regulation. The attenuating plates are an integral part of a replaceable cartridge, and are specifically designed to obtain a number of significant control advantages, such as reduction of noise, high frequency vibrations and cavitation. This advanced trim allows a bi-directional control of the flow.
