Home Electrical Motors and Generators An electric motor is an electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor’s magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor’s shaft. Electric motors can be …
Home Types of Butterfly Valves (API 609) A butterfly valve is used to shut off or modulate the flow of a fluid (isolation and regulation). API 609 Centric butterfly valves (soft seated) are preferred to gate and ball valves for low-pressure and non-critical applications as they are cheaper, lighter, and easier to install. Eccentric butterfly …
Home Globe Valve BS 1873 and API 602 What is a globe valve? When shall it be used instead of gate and ball valves? In this article, we illustrate the scope of this type of valve (which is, in a word, to regulate the flow), the differences with other types of valve, the alternative designs, …
Home Plug Valves Plug valves are quarter turn operated and can be Lubricated or Non-Lubricated. Lubricant is injected under pressure between the plug face and body seat to reduce friction, provides port sealing and allows sealant jacking action to unseat the plug-in tapered designs. The Non-lubricated type shows mechanical design characteristics capable to reduce friction …
Home Check Valve BS 1868, API 6D, API 602 A check valve prevents potentially damaging backflows to protect equipment like pumps and compressors. Non-return valves allow the flow of the fluid in one direction only and block reverse flows. This type of valves is available with cast and forged bodies (BS 1868, API 6D, API …
Home Types of Ball Valves (Floating, Trunnion) A ball valve features a spherical disc to open and close the flow of the fluid. They are the industry standard for pipeline shut-off applications, as their design guarantees very tight and leak-free sealing even after years of operation. The two key types of ball valves are the …
Home SAFETY VALVE APA provides state of the art safety valves according to various international standards. They are used for emergency situations where pressure or flow must be redirected in a safe condition. BLOW OFF VALVE Safety valves protect the plant components against over pressure. MAIN FEATURES • Nominal size: DN3-DN89 or bigger • Nominal …
Home Control Valves A control valve is a valve with a power positioning actuator for moving the valve plug to any position relative to valve port or ports in response, and in proportion to, an external input received. The opening or closing is commonly operated by electrical, hydraulic, or pneumatic actuators. Usually a modulating valve …
Home Subsea Ball Valves We offer a range of valves for Subsea Applications qualified to the latest international Standards. Subsea production and pipeline transmission are considered critical service applications for valves because of the high pressures, extreme temperatures, and remote location of the equipment. APA has experience in offers a range of ball valve sizes …
Home Valve Actuators Pneumatic Electric Hydraulic A wide range of subsea mechanical gears and hydraulic actuators (linear and quarter turn) tailored to meet Customer requirements with the highest level of performance and reliability. Valve actuator is a mechanical component device used to operate the valve using power source. It can be Manual, Electric, Pneumatic, or …
