Manual valves are primarily used to stop and start the flow (block or on-off valves), although some designs can be used for basic manual throttling. The best manual valves for on-off services are those that allows flow to move straight through the body, with a full area closure element that presents little or no pressure drop. various valve sizes from ½’’ up to 60” are available.

ball valves are designed to meet the requirements of the process industries with improved process safety and efficiency. Our well known brands with proven technology in design, materials and coatings enhance process reliability in the most demanding shut-off and control applications. A wide range of valve size from ½’’ up to 60” are available with certifications include fugitive emission, fire-safe and SIL 3.
A control valve is a device capable of modulating flow at varying degrees between minimal flow and full capacity in response to a signal from an external control device. The control valve, often referred to as “the final control element,” is a critical part of any control loop, as it performs the physical work and is the element that directly affects the process.
A control valve is comprised of an actuator mounted to a valve. The valve modulates flow through movement of a valve plug in relation to the port(s) located within the valve body. The valve plug is attached to a valve stem, which, in turn, is connected to the actuator. The actuator, which can be pneumatically or electrically operated, directs the movement of the stem as dictated by the external control device.
PMP provide and supply well-known Control Valves brands which are available with a wide variety of valve bodies in various styles, materials, connections and sizes.
A safety valve is an automated mechanical device used to regulate a fluid’s flow through a process system in conformance with predetermined pressure and temperature constraints to prevent an incident that could result in the loss of life, assets or harm to the environment.
Safety valves are also known as pressure relief valves (PRVs), pressure safety valves (PSVs) and relief valves (RVs).
