Automated On/Off and Modulating Control Valves.
Automated valves can be operated with electric, pneumatic, electro-pneumatic, and electro-hydraulic powered actuators. Actuators allow valves to be operated automatically by a control system or manually from a remote location. Valve automation brings significant advantages to a plant in the areas of process quality, efficiency, safety, and productivity. Click on the desired valve type to continue with your selection.

Select Angle Valves
Angle-Seat Valves are operated with a piston actuator. These compact pneumatic valves are ideal for on-off valve applications and an excellent alternative to more expensive automated valves. High flow rates are obtained with the streamlined flow path. These reliable, low maintenance valves can be fitted with a comprehensive range of accessories for positioning, indication, and manual override.

Select Ball Valves
Ball valves are reliable and simple to use as a shutoff valve or flow metering valve. Just a quarter turn of the handle opens or closes the valve. Handle position lets you "see" the valve's position.

Select Butterfly Valves
Butterfly valves are used where economical, high capacity valves are needed. Resilient liners provide bubble tight shutoff in general service applications. High-performance butterfly valves provide excellent flow control, and Triple offset metal seated butterfly valves are designed for high pressure and high temperature severe service applications.

Select Control Valves
Control valves modulate the flow of fluids in flow, pressure, level, and temperature control systems. They consist of three main parts: a valve body, actuator, and positioner. The positioner, through the actuator, drives the valve in proportion to a control signal. Various types of valve and actuator combinations are available to suit most process control applications.

Select Diaphragm Valves
Diaphragm valves have excellent shut-off and flow control characteristics. A flexible molded diaphragm regulates flow, provides tight shutoff, and isolates the fluid from the environment. The valve consists of the body, diaphragm, and handwheel assembly. Their simple design and wide choice of materials make them ideal for corrosive, abrasive, and sanitary services.

Select Float Valves
Float valves automatically control liquid level and prevent overfilling tanks. The valve is operated mechanically by a float which rests on top of the liquid. As the liquid level rises, it pushes the float up and closes the valve. As the level falls, the valve opens. The amount of liquid pressure the valve can shutoff against is determined by the length of the rod and size of the float.

Select Gate Valves
Gate valves have a sliding wedge or disc which reciprocates into and out of the valve port. These valves are ideal for isolation of general purpose as well as high pressure and high temperature applications where operation is infrequent. Manual operation is accomplished through a multi-turn handwheel assembly.

Select Plug Valves
Plug valves are similar to ball valves except instead of a spherical element, a cylindrical element is used as the internal restriction. Plug valves are typically more expensive than ball valves, but they are inherently more rugged as well. The plug is guided by a sleeve which acts as the sealing member. These valves are available in 2, 3, and 4-way configurations.

Select Solenoid Valves
Solenoid Valves are simple electrically operated devices. The valve plug is held in place by a spring. When electric power is applied to the solenoid (Energized), the current draw through the coil generates an electromagnetic force which opposes the spring, causing the plug to change position. When power is taken away (De-energized), the spring returns the plug to the normal position.
