The Jarecki HSV Series ball valve is a premium valve for very demanding services . HSV Series valves are used for applications in the Power and Pulp and Paper Industries.
A double seal design providing both spring loading and excellent sealing capabilities. There is no area for media to build up behind the seat, which prevents the valve from locking up.
For unidirectional applications. The sealing seat is available as a separate seat ring for reparability, or integral with the tailpiece for high temperature applications. The spring seat OD seal prevents media from building up between the spring and the back of the seat.
A series of Graphite seal rings behind the metal seat prevents media from building up behind the seat. The rings also allow for expansion of the internal valve components in high temperature applications. This design is great for applications involving fine solids as the graphite prevents the media from building up behind the seats.
The T Seat Style designates a soft seat material. There are many seat materials available with TFM being the standard option. A metal lip on the body and tailpiece provides fire safety and meets API 607 requirements.
Valves that handle fluids and gasses that tend to deposit crustations or leave residue on the inner valve surfaces will become hard to operate. With the Ball Valve in the closed position for lengthy time periods, the buildup of deposits adhere to the ball face within the seat boundaries causing interference with the valve seats during attempts to cycle the valve. Only a few thousandths deposit on the ball face will increase turning torque and damage the seats. Excessive crustations or residue on the ball face will make the valve inoperative.
The Phantom Port solves this problem. This feature is a circular recessed area machined into the ball. It is machined in dome configuration to maintain ball strength. Since this area is below the ball OD, the media residue passes safely below the seat when the valve cycles. Because less area is contacting the seat when the valve cycles, there is 75% less seat wear on every cycle.
Valves covered in this bulletin are available to conform to the following industry standards and specifications

Jarecki Valves has been an American valve manufacturer and rebuilder for more than 40 years, providing customers with high quality metal and soft seated ball, control, and check valves. Jarecki Valves got its start engineering and manufacturing valves for the Navy Nuclear Industry, which involved working with exotic materials and manufacturing valves for critical service. In 1980 Jarecki Valves worked closely with Hammermill Paper and developed the HSV series to handle all the critical applications at the mill. Jarecki is now using the experience in providing quality valves for today’s industries.
Jarecki supplies valves to a variety of industries. Some of which include Pulp and Paper, Chemical, Petrochemical, Power, Oil and Gas, Mining, and Municipal.
