Solenoid Valves - (1022 companies)Solenoid valves are devices that use a solenoid to control valve activation. They are considered electromechanical control devices used to control liquid or gas flow. An electrical current runs through a coil to control the valve by moving a plunger...Valve TypeSingle SolenoidDouble Solenoid -
Hydraulic Valves - (684 companies)Hydraulic valves contain and transfer the flow and pressure of hydraulic fluid in hydraulic power systems. They range from simple shutoff valves to precision control valves. In their unpowered state, hydraulic valves can be normally open (open... -
Check Valves - (1951 companies)Check valves are self-activating safety valves that permit gases and liquids to flow in only one direction, preventing process flow from reversing. They are classified as one-way directional valves. Check valves are self-activating safety valves... -
Butterfly Valves - (1270 companies)Butterfly valves control flow through a circular disc or vane by turning the valve's pivot axis at right angles to the direction of flow in the pipe. They are normally used as throttling valves to control flow. Butterfly valves are quarter-turn... -
Gas Valves - (535 companies)Gas valves are used to handle and control the flow of gaseous media such as liquefied petroleum and natural gas. They are made of metal or plastic and vary in terms of valve size, pressure rating, number of ports, and flow. Gas valves are flow... -
Gate Valves - (1164 companies)Gate valves and knife valves are linear motion valves in which a flat closure element slides into the media stream to shut off flow. Gate valves (also known as knife valves or slide valves) are linear motion valves in which a flat closure element...
-
Globe Valves - (794 companies)Globe valves are linear motion valves with rounded bodies, from which their name is derived. They are widely used in industry to regulate fluid flow in both on/off and throttling service. As their name suggests, globe valves are linear motion valves...
-
Ball Valves - (2114 companies)Ball valves are quarter-turn, straight-through valves that have a round closure element with matching rounded seats that permit uniform sealing stress. The valve gets its name from the ball that rotates to open and close the valve. Ball valves...

ValvTechnologies, Inc.
Coking Valves Decrease unscheduled downtime and possible production losses with ValvTechnologies ' coker valves. The delayed coker process is a batch process, one of the most hostile environments in the refinery due to the abrasive and erosive properties of the coke by-product - and is crucial to a refinery 's profitability. Valves are cycled frequently and failure can lead to a complete shutdown of a unit, resulting in large process and financial costs. Optimizing valve life-cycle is critical to operational...
