Model PCU-1 - Used with the PC-1 Service Tool

Model PCU-1 Upstrain Unloader is designed to equalize tubing and annulus pressures above a PC-1 Retrievable Cementer Packer or other makes of upstrain actuated tools that are compatible in operation with that of the unloader.

The unloader is made up directly above the PC-1 Cementer Packer and is usually run in the hole in the open position to allow fluid bypass through PC-1 and into the annulus. Torque is transmitted through the unloader to the PC-1 by a key located in a key-slot of the unloader body. Applying upstrain to set the PC-1 will close the unloader and setting down weight will open it.

• Unloads pressures from either direction
• Multiple acting, May be run in either open of closed position and then opened to closed as many times as required
• Full opening bore through tool
• Easy operation, Set down weight to open and apply upstrain to close
