Control Valves (Pneumatic Globe Control Valves)

puneumatic actuator control globe valve (2)

Laminar designs, manufactures and supplies pneumatic control valves to the chemical industry, water & wastewater treatment plants, desalination plants, for power plants as well as the petrochemical industry.

Laminar globe control valves designed to regulate the flow rate, pressure or temperature of liquids, gases or vapors and are used even under tough applications such as for industrial water and wastewater treatment plants or chemical/chlorine applications as well as for chemical and milk of lime systems.

High-performance valve actuator:
Our pneumatic multi-spring actuators, with reliable construction, are characterized by short actuating times, improved actuating forces, and tight sealing. Our control valves are also available with electric or electrohydraulic actuators.

Smart Positioner:
Our digital positioner is a multi-functional interface with integrated support for the controller or process control system. Mechanical/analog electro-pneumatic IP positioner is also available.

Reliable stem seals:
Our technical team can precisely tailor the stem seal to suit the process fluid, pressure, and temperature required. The design, stem surface, and packing material support each other perfectly to avoid issues with friction, corrosion, and emissions.

Robust, high-precision valve trims:
particularly designed to prevail flow conditions in your plant. The shape, seats and material from which they are made are optimized to meet your operation’s requirements.
