Kerotest^® Manufacturing

The new Kerotest 3/8-inch Large Bore Manifolds offer some major benefits over standard bore manifolds when used in on-shore and off-shore applications. By minimizing gauge line error, they ensure the accuracy of the measurement unit pressure readings that are used to calculate flow. And the improved line drainage eliminates problems associated with wet gases and hydrates.

Like standard Kerotest manifolds, these new Large Bore models are designed to capably perform isolation, equalization, bypass, test, and vent operations without the need for external piping, since the required piping is internal to the manifold.

The Kerotest 12-inch Polyball full port polyethylene ball valve is big and it delivers big. This large bore model boasts the highest flow of any 12-inch polyethylene ball valve made in America today. It’s full of the big design, engineering and production benefits that have made us one of the leading manufacturers of polyethylene ball valves in North America.

Kerotest Polyball polyethylene ball valves for natural gas reflect a 100-year commitment to the gas distribution industry. These valves are American made, supported and distributed, with ample inventory at all times. You will find full port and reduced port sizes from .5-inch to 12-inch IPS; metric sizes from 20mm to 315mm, and available High Head Extensions in varying heights to meet specific installation requirements.

All Polyball valves feature the industry-standard tracking and traceability code per ASTM F2897 that allows instant access to individual valve specifications. With decoding software, simply scan the bar code to see the production date, size, material and valve type, lot code and more.

In some of the most extensive tests performed on a valve, the Kerotest Weldball Gas Distribution Valve consistently meets and exceeds industry standards for design and performance.

The Weldball full port and reduced port valves come in butt weld, flange, and weld by flange configurations. Class 150 Reduced Port valves are available in sizes .75-inch through 12-inch, while the Full Port valves are available in 2-inch through 10-inch. Class 300 Reduced Port valves are available in sizes .75-inch through 8-inch, while Full Port valves are available in 2-inch thru 8-inch. And, of course you can count on zero leaks, no maintenance and no required lubrication or adjustments.

Each valve is high-pressure air tested to insure integrity and leak tightness. Use it with confidence in distribution services, meter and regulator stations, system blow down applications, hot tap applications and other applications that demand a positive shut-off.

The Kerotest Model-1 Steel Gate Valves feature metal-to-metal seats, the lowest operating torque in the industry and a patented packing to ensure no environmental leakage. Choose from a full size range of 1-inch to 16-inch with a variety of end configurations and 285 to 740 WOG.

The Model-1 also features a full range of options and accessories that include watertight high head extensions, operating square extensions, malleable iron circular hand-wheels, epoxy coating, body bleed taps and vent pipes.

The EV-11 Soft Seated Valve is an economical field-proven, full opening, non-rising stem gate valve. This unusual gate valve incorporates an exclusive “elastomer seat” seat design – a simple method which solves leakage problems without requiring lubrication or conventional seat inserts. Available in 2-inch through 12-inch full port; Class 150, 500 WOG and Class 300; flange, weld and weld by flange end connections.

This remarkable general service valve is ideal for natural gas distribution applications including manifolds, flow lines, regulator stations, and meter runs. The full-opening, uncomplicated design of the EV-11 soft-seat gate valve makes it ideal for water, oil, and other liquid applications.

These T-Strainers, which provide up to 30 percent larger basket area, are manufactured of carbon steel to ensure strength, precision, and long-life. Available in standard sizes from 1-inch through 6-inch, ANSI 150/300 pound, Kerotest can also deliver t-strainers in larger sizes as needed.

Kerotest T-Strainers are interchangeable in valves with Standard ANSI B16.5 & 16.10 end-to-end dimensions. They also feature an elastomeric basket seal that eliminates potential leakage between the basket and body, as well as a reversible basket that readily accommodates reverse flow applications.

These valves provide extra pressure outlets, permit line samplings, isolate gauges, provide a bypass, and eliminate extra connections and parts on a gauge leg, thereby reducing cost and increasing dependability. Kerotest/Marsh “N” Series Needle Valves are used in processing plants, oil and gas production, hydraulic and pneumatic equipment, testing labs—anywhere the flow of fluid must be carefully regulated.

A rugged, forged construction delivers dependable, leak-free performance at high and low pressures. Designed to measure and regulate flow in processing plants and oil and gas production applications, these valves perform in tight spaces and resist low-level corrosiveness. With optional trim, they also resist sour fluid environments, caustic liquids, and corrosive media.

The Kerotest Double Block & Bleed Needle Valves are built for applications with pressures up to 10,000 psig (689 bar). The design combines isolation and venting in a single valve, eliminating the need for tubing and fittings. This operator-friendly valve design features fully captured stems, consistent sealing during system depressurization or repressurization under a range of pressures, and a low-torque, easy-turn ergonomic handle.

The KPT two-valve manifolds are used primarily to calibrate static pressure transmitters, switches, or gauges. All necessary hardware including a shutoff valve, calibration valve, tee, and other tubing are all contained in one product. The KPT series of manifolds are available with either replaceable soft seats or an integral metal seat. The KPTM manifold includes a special valve seat that can be converted from a hard or metal seat to a soft seat by simply removing two washers. The KPT7 manifold is intended for high temperature applications. It has an integral metal seat.

The Kerotest Model 1 Steel Gate Valves feature metal-to-metal seats, the lowest operating torque in the industry and a patented packing to ensure no environmental leakage. Along with a 1-inch to 16-inch size range, a variety of end configurations and 285 to 740 WOG, we offer a full complement of options and accessories.

Customize your gate valves with locking devices, watertight high head extensions, operating square extensions, malleable iron circular hand-wheels, indicators, epoxy coating, body bleed taps, and vent pipes.

The KM6A 5-Valve Manifold is designed specifically for natural gas applications, especially for use with recording orifice meters. These manifolds are generally mounted in the tubing from the orifice flange. Because of its light weight, it is normally supported by the meter tubing without additional support. The KM6T and KM6TA options, however, allow for flange-by-tube installation or flange-by-flange installation of these manifolds if desired.
