Pull cable at 160 ft./minute

Designed to pull CIPP liners, fold and form liners, and specialty sliplining, the Grundowinch hydrostatic constant-tension winch can pull up to 3,280 ft. of 3/8-in. cable. In addition to a 3-ton pulling capacity, it offers variable-speed control throughout the pulling range. TT Technologies. www.tttechnologies.com.

Reduce sediment buildup

These 30-in. and 36-in. gate valves have taken the century-old double-disc design and integrated it with the latest resilient seated-gate valve design and technology. They feature CleanTrack technology, technology, which uses a roller-scraper system that automatically cleans the track in the valve body when the valve is closing. Less sediment buildup makes for improved performance and reduced maintenance. M&H Valve Co.. www.mh-valve.com.

No concrete thrust blocks needed

Eagle Loc 900 is an internal joint restraint system designed for open-trench construction of pressure pipelines where pipe-to-pipe and pipe-to-fitting joint restraint is required. It is available in DR18 in diameters ranging from 4- to 12-in. PVC pipe for use in distribution, pipelines of potable water, municipal water systems, force main sewers, and water reclamation projects. JM Eagle. www.jmeagle.com.yfvdfdzdrbywwacuw

Record fusion pressure

The Wired DataLogger offers supervisors the ability to record and document the pipe fusion process. Built for fusion sites that require up to 4,000 psi, it does not use Bluetooth communications like its wireless predecessor, which allows it to work on jobsites with restrictions on wireless communications. It uses a Microsoft Windows user interface and the ability to transfer data to a desktop computer through a USB port and Microsoft ActiveSync. McElroy Manufacturing Inc. www.mcelroy.com.

No insert stiffeners required

The Handy-Loc stab fitting is designed for ¾-in. and 1-in CTS (H) & PEP (-3H) plastic tubing. No insert stiffeners are required for it. Tube fit reduces the chance of dirt unseating the gripper. It can be disengaged from the tubing without the use of special tools, and features color-coded grip rings. A.Y. McDonald Mfg. Co. www.aymcdonald.com.

Variable-speed AC drive

The Altivar 21 variable-speed AC drive controller series operates buildings with greater efficiency. The series uses three-phase AC motors from 1 to 40 hp at 208/230 Vac and 1 to 100 hp at 380/460 Vac. Schneider Electric. www.schneider-electric.us.

Calibrate from 100 ft.

The Remote Gas Calibrator for the IR400 Infrared Point Gas Detector makes it easier to calibrate remote-mounted infrared gas detectors. It permits users to test and calibrate the IR400 and its predecessor, the IR2100, from as far away as 100 ft. It does not affect sensor response, as evidenced by T50 response times of 6 to 7 seconds and T90 response times of 10 seconds, and is suitable for operation at maximum air velocities of 30 mph. Easy to install and use, it requires no electrical wiring or connectors. General Monitors. www.generalmonitors.com.
