PML has the largest portfolio of actuation and controls products available in the market. We have the applications experience and customization capabilities to find the optimum solution for your valve automation needs.

Actuator Products

Internal, relief, emergency shutoff, globe, angle, transfer and bypass valves are installed on inlets and outlets of pressure vessels and in piping systems. They provide a means of withdrawing and filling product with or without pumps and compressors.

Bulk Storage & Transport Equipment Products

Control Valves

Reliable Fisher control valves help you meet production schedules, maintain product quality, and improve plant efficiency.

Controllers & Instruments

Poor valve reliability, performance, or productivity can undermine your process operations. Ensure your assets are working the way they are supposed to with our trusted and tested controllers and instruments.

Flame & Detonation Arrestors

We offer a wide variety of flame and detonation arrestor products with maximum flow to pressure drop characteristics. Our portfolio includes in-line, free vent, deflagration and detonation flame arrestors. Enardo flame arrestors use spiral wound, crimped-metal ribbon flame cell elements to inhibit flame propagation by absorbing and dissipating heat. Connection sizes range from 3/4 inch up to 36 inches.

Isolation & Shutoff Valves

We understand you are constantly faced with the need to safely and effectually control many different types of processes. We offer an extensive isolation valve portfolio comprised of trunnion ball valves, floating ball valves, high performance butterfly valves, triple offset valves, slam-shut valves, and shut off valves. These valves are designed and tested to provide the performance necessary to keep your processes safely operating at maximum efficiency.

Pressure Relief & Safety Valves

Industry leading pressure and safety relief valve designs with over 140 years of technical and application expertise providing custom engineered solutions for O&G, Refining, Chemical, Petrochemical, Process and Power applications. Our designs meet global and local codes and standards (API 526; ASME Section I, IV & VIII; EN ISO 4126; PED & more). Gain insight into the performance of your pressure relief valves with wireless monitoring.


Ensure superior pressure management with Emerson’s pressure regulating products for compressed air, natural gas, steam, fuel, propane, specialty gases, water, and other process fluids. Our suite of products offers design innovation and durability even in the world’s most rugged environments. From Fisher direct and pilot operated regulators to TESCOM  high pressure control regulators, Emerson offers the industry’s broadest portfolio of pressure control technologies, enabling dependable solutions.

Steam Traps, Valves, and Level Gauges

We have a broad portfolio of steam solutions includes thermodynamic, thermostatic and mechanical steam traps; blow-off and blowdown valves for removing sludge or dissolved solids from the boiler drum; gauges for monitoring the boiler drum water level and automatic recirculation control (ARC) valves for protecting the boiler feed pump. Our experts can conduct steam system surveys and recommend solutions to ensure optimal operation and enhance energy efficiency.

Tank Vents & Hatches

Our solenoid valves set the industry standard for reliability and reduced power consumption, featuring a complete line-up of directional control, proportional and microfluidic valves designed and customize-able for next generation industrial food production, medical equipment, nuclear facilities and other rigorous applications. Whatever your application need, our world class engineering teams can work with you to create high-quality custom assemblies.
