PF-1 Phase Flow™ – Initiator Injection Pump The Model PF-1 pump represents a breakthrough in intensifier technology. The independent nature of the PF-1 allows “phasing” of the HP cylinders. This unique feature pre-loads the catalyst in the second cylinder while the first is on its power stroke, essentially eliminating the pressure drop associated with shifting the supply from one cylinder to the other. With this innovative Technology the temperature profile within the reactor will get much smoother, allowing you to run closer to the optimum setpoint. As improved rates can be achieved, the...

Lubrication and Catalyst Feed Letdown and Recycle Service Inline Poppet Check Valve Poppet check valve designed to address the “hotcheck” problem common to many hyper compressor lubrication systems. Other applications may include catalyst/modifier delivery lines and reactor entry points. Process Control Valve (PCV) Valves are manufactured from selected heat-treated alloy steel forgings. Valve body and trim designs are furnished to meet customer specifications for particular service. Available pressure ranges are 5.000 to 75.000 PSI. Valves furnished with Electro-hydraulic or Pneumatic...

PMH Reciprocating Catalyst and Modifier Injection Pump The KMT McCartney Model PMH hydraulic driven reciprocating metering pump has long been the industry workhorse for initiator and modifier injection. The PMH is equipped with pneumatic controls. Pump units are available in single configuration or in a dual configuration when space is a consideration. Single and dual pump units are supplied with manifolded process suction and discharge piping with single point connections. Cooling jackets are available when initiator flashing is a concern. Electric motor driven hydraulic power units are...

Rings / Injection / Strainer Lens and Cone Rings Line Strainers Cone Ring and Lens Ring gaskets can be fabricated in any size according to customer specifications, or we can design the parts to suit your working conditions. Materials will be selected per customer specifications or according the specific application. KMT McCartney can design and provide line strainers of any size to fit your working conditions, eliminating larger debris from your system before causing major problems down line. Materials will be selected per customer specifications or according the specific application....

Valves Dual Let Down / Vent Valve High Speed Vent Valve This unique design configuration combines the Product and Vent Valve, allowing for a very compact and efficient valve package. The dual valve design reduces the length of “dead leg” gas to an absolute minimum, greatly reducing related problems such as gas degradation in that area. The KMT McCartney High Speed Vent Valve combines the 2piece KMT McCartney vent valve design and pneumatic actuator with external manifold and oversize solenoid valve. The Let Down body mounts directly to an Autoclave Reactor discharge or it can be spooled to...

Process Control Valves (PCV) Process Control Valve Positive Position Process Control Valve The KMT McCartney PCV is a modern design of the Fisher CZA industry workhorse. This valve is dimensionally interchangeable with valves in service today. The KMT McCartney Positive Position Process Valve incorporates the Limitorque™ L120 Series electric motor driven gear actuator. This robust KMT McCartney / Limitorque™ combination eliminates unintended valve cycling and provides dependable service day after day under the most demanding conditions. The L120 actuator is available in weatherproof and...

Check Valves / Gear driven Valves Manual Gear Actuated Valve Inline Poppet Check Valve All KMT McCartney designed valves are available with 3:1 or 6:1 ratio gear actuators. Housings are made of steel, precisely machined internally to accept precision steel drive and pinion gears. Bronze bearings provide smooth operation of the hand-wheel and actuator stem. The actuators are capable of producing stem loads up to 50.000 lbs. (22.700 kg) with a hand-wheel torque of 100 ft-lbs. or less. KMT McCartney’s new poppet check valve was designed to address the “hot check” problem common to many hyper...
