Piggable Diverter Valves
solid seat ball valve
For non OBSTRUCTED pRODUCT TRANSFER
The Solid Seat Ball Valve (SSBV) is a three-way piggable diverter valve specially designed by HPS to allow non obstructed product transfer. This can be from one source to two selectable positions, or from two selectable product sources to one destination.

optimum efficiency with the ssbv
The SSBV can be completely dismantled and offer a clear passage, which means no pressure loss. It provides optimum efficiency for pigging situations and has been designed for use with HPS pigs, although it can be used in installations without pigging to aide process routing.
can be used as pig launchers
When using a HPS SSBV as a Pig Launcher, it takes away the need for a traditional two valve ‘T’ launch arrangement. This single valve arrangement can be attached to the outlet port of the pump and allows product to pass through a full bore path while in the Transfer Position. When transfer is complete the valve will rotate to the Pig Launch Position, opening a path for the Pig to enter the transfer line, while blocking the path from the pump outlet port.
The Pig is isolated in an offline housing when not in use, allowing access for Pig inspection or replacement during normal product transfer. These Pig Launchers can be mounted in the horizontal or the vertical orientation.
Piggable Sweeping Bend
The solid stainless ball within the valve comprises a 120° piggable sweeping bend, which allows for smooth passage for the HPS Pig. The ball rotates 120° between ports allowing for unobstructed product flow and no pressure loss.
Can be Easily Dismantled
The valve can easily be fully disassembled, allowing for easy maintenance and cleaning. The PTFE seals sit on O-rings within the flange allowing for a floating seat arrangement.
