The Firechek® FC-4 Series valve is a FM Approved heat activated pneumatic shut-off valve. When the FireChek senses excessive heat from a nearby fire, it immediately vents the pneumatic actuator and closes the actuator air supply line. FireChek triggers quickly, securing pneumatically operated process line valves. Because this valve responds to heat, not flame, it offers dramatically improved protection compared with conventional plastic tubing burn-through. It shuts off the air supply line to prevent plant air from feeding oxygen to a fire.

Features & Benefits:

• Rapidly responds to temperature rise, NOT flames
• Vents actuator air pressure
• Closes actuator air supply line
• Needs no power source, self activates
• Compatible with ALL pneumatic actuators
• No contact with process fluids
• Easy to test and reset
• Reliable, intrinsic triggering
• Easily retrofit, installs in minutes

Palmer Wahl Instrumentation Group is excited to announce the rollout of our newest product, the Multi-Thread Pressure Tester (MPT), a patented Pressure Tester that has multiple thread sizes in each tester. This revolutionary design saves time and money for operators that are testing pressure lines in the gas, plumbing, sprinkler, and HVAC industries, to name a few. Tried and tested in the field, MPT will change the way you think about pressure testing.

Palmer Wahl owns the patent on the MPT, and we will be marketing the testers throughout the United States and Canada. There is a five year warranty on the tester which is Made in the USA out of airplane aluminum. The MPT can be found on the Palmer Wahl website, and coming soon to its own dedicated site at PalmerMPT.com.

Current customers are finding that the MPT saves them time, no more running around trying to find ties, manifolds, and proper size threads to reduce down or up to the size needed to test for pressure leaks in piping systems that are being installed or repaired. So the labor saved, cost of extra parts saved, and the flexibility of being ready for your initial testing and inspections is priceless.

Available in quarter-turn, rotary and linear versions, robust Rotork CMA actuators perform numerous process control valve, metering pump and damper applications. Single-phase or DC electrical power is all that is required for simplified installation and control valve actuation in safe or hazardous areas. Explosionproof certification to international standards is available.

The latest ‘Performance Plus’ development introduces a user selectable increased shut-off torque/thrust option. Developed in response to industry feedback, this option enables a more tailored and cost-effective sizing regime to be applied to both the modulating and tight shut-off demands of the control valve. A tight shut-off is often required as part of the valve duty, leading to potential over-sizing of the actuator for mid-travel modulating operations. The increased torque/thrust option is selected and configured during the actuator set-up programme, as part of a logical menu-driven process using an internal electronic LCD display and pushbuttons.

A new model size has also been introduced to the rotary CMA design, creating a range that is suitable for virtually all process control applications. Upgrades to internal electronics and HMI enhancements complete the list of improvements across the range. For additional functionality, all rotary CMA actuators have output speeds that are adjustable down to 50% of full speed, in 10% increments.

The maintenance-free CMA drive train, permanently lubricated and environmentally protected to IP67, can be mounted in any orientation. Accepting an industry-standard 4-20mA control signal, the CMA provides accurate and repeatable positional control. Resolution is 0.2% on linear and quarter-turn applications and 2 degrees on the multi-turn models.

Manual operation is available as standard whilst optional extras include local pushbuttons and selector switch, digital position indicator and network compatibility with Rotork Pakscan, HART®, Profibus®, Modbus® and Foundation Fieldbus®.

In the latest development of its successful range of CMA electric control valve actuators, Rotork has introduced a new version specifically designed for the demands of choke valve operation.

Built with extensive industry experience, the CMR-250/GB3 actuator meets exacting requirements for low power, high torque modulating control in a compact package for applications including severe service upstream wellhead production and injection valves. The low power requirement and a 24VDC option enables solar powered and battery back-up supplies to be introduced in remote locations, whilst the all-electric technology delivers considerable system simplification and economy in any environment by eliminating the on-going costs associated with an instrument air supply.

Easily adaptable to suit any type of valve, the CMR-250/GB3 delivers a maximum output torque of 45 Nm (400lbf in). Available for a range of single-phase or DC power supplies, the design combines a brushless motor with permanently lubricated, high efficiency gears to achieve accurate, responsive and continuous modulating control. Rotary output speed is adjustable down to 50% of full speed.

The compact actuator enclosure is environmentally sealed to IP67 as standard and available with ATEX, IECEX, FM and GOST hazardous area certification. The wide ambient operating temperature range (-20 to +65ºC for explosionproof models and -30 to +70ºC for watertight models) facilitates long-term reliability and maintenance-free operation in the harshest of environments.

Actuator set-up is performed in a logical menu-driven process using an internal electronic 6-segment LCD display and pushbuttons. User selectable adjustments encompass speed, dead band, zero and span, command signal type, standard or reverse action and loss of signal position. A standard 4-20mA signal is used for control and feedback, whilst digital network options include Rotork Pakscan, HART®, Profibus®, Modbus® and Foundation Fieldbus®. A hard-wired RIRO (Remote-In-Remote-Out) option is also available.

As with all Rotork products, the CMR-250/GB3 actuator is backed by the worldwide sales and service network of the Rotork flow control group, providing a local source for complete support in every territory using fully trained engineers.
