What is a Camflex valve?
The Camflex II valve is a heavy-duty, automatic-throttling control valve that incorporates the following features: • The flangeless body rating is a rugged ANSI Class 600. • Heavy-duty guide lugs assure quick, positive alignment during installation.
How does a Camflex valve work?
The heart of the Camflex valve is its eccentric plug. The eccentrically rotating, double offset plug CAM’s into and out of the seat. This camming action eliminates friction throughout its rotation since the plug moves away from the seat as it opens, unlike other rotary valve types.
What is a rotary globe valve?
A new rotary control valve is presented which combines a conventional linear globe body with a rotary stem in a simple and innovative way. The flow channel is similar to that of conventional linear globe valves, which improves cavitation resistance compared to standard rotary valves.
What is an eccentric plug valve?
What is an eccentric plug valve? A style of rotary control valve with a plug-shaped, flow-restricting member that follows an eccentric path as it rotates. The plug has no contact with its seat until it turns within a few degrees of the shutoff position.
What is a rotary control valve?
Rotary Control Valves. The rotary control valve is a directional control valve actuated in a rotary motion. With high pressure and zero-leak performance, the valve is designed and manufactured to meet your requirements for both topside and subsea applications.
How does a plug valve work?
The plug valve uses a mechanism that rotates between the open and closed position and protects both seals from the flow path. During rotation there is no contact between body and seals, and slips expand onto the body seat when the valve is closed to avoid causing any wear or abrasion to the seals.
Is globe valve linear or rotary?
A globe valve would be an example of a control valve with linear motion.
What is the difference between sliding stem and rotary shaft valves?
A sliding stem valve has a direct connection between the actuator shaft and the internal flow element trim (e.g., plug). The motion is linear and direct. The installed characteristic for rotary valves tends to become too flat at upper valve positions (i.e., more open); valve gain becomes too low.
Is a plug valve a gate valve?
Like the gate valve, a plug valve has an unobstructed flow, yet requires only a 90 degree turn to open it. However, plug valves are available in much larger sizes than ball valves and are highly suitable for use in wastewater plants.
What is a rotary valve 2 stroke?
A rotary valve in the form of a flat disc, also known as a disc valve is widely used in two-stroke motorcycle engines, where the arrangement helps to prevent reverse flow back into the intake port during the compression stroke.
What is the difference between plug valve and gate valve?
Slab style gate valves have seats that are spring energised. All these valves are made in metal to metal and soft seat configuration. PLUG VALVES. Plug valves are valves with cylindrical or conically-tapered “plugs” which can be rotated inside the valve body to control flow through the valve.
Which is better the camflex GR or globe valve?
Camflex GR’s rotary design has several advantages over the typical reciprocating globe valves that it replaces. At the heart of the Camflex is the double eccentric plug design. Eccentric rotating, self-aligning plug results in reliable shutoff and fewer leaks.
How does a camflex rotary control valve work?
The heart of the Camflex valve is its eccentric plug. The eccentrically rotating, double offset plug CAM’s into and out of the seat. This camming action eliminates friction throughout its rotation since the plug moves away from the seat as it opens, unlike other rotary valve types. This ensures precise control at all openings.
Can a rotary valve replace a globe valve?
This new type of valve converged the best control features of a conventional globe valve with a rotary action to produce a valve capable of replacing at least 80% of the control valves in use at that time.
What kind of control valve is Masoneilan camflex?
The Masoneilan Camflex valve is designed first and foremost to be an excellent control valve and has proven to truly be a Universal Rotary Globe control valve. The heart of the Camflex valve is its eccentric plug.
