It can perfectly avoid problems of friction, corrosion, and emissions.
It is of low center of gravity, high vibration resistance and easy to install.
Simple to control, rapid response, and intrinsic safety, no need to take additional explosion-proof measures.
Fluid channels in a s- shaped streamline, small pressure drop loss large flow, wide adjustment range, high precision flow
COVNA pneumatic control valve has good adjustment stability. For the working conditions with large pressure difference, the cavity of the valve body is enlarged, which improves the buffer capacity of the valve body

FAQ
Q: What is the difference between Normally Open and Normally Closed valves?
A: As the name suggests, Normally Open valves allow air to pass when they are not energized (or actuated). Normally Closed valves must be actuated to allow air to pass.

Q: What is the life span of your pneumatic actuators?
A: We have passed 1 million times of product quality test, and obtained the certificate

Q: Does the air actuated valve have a manual override?
A: The air actuator does not have a manual override, but a manual override is provided with optional direct mount solenoid valves.

Q:How fast does an air actuated valve operate?
A: See product specifications. Generally, smaller valves less than 2 inch pipe size, cycle in about one second. Larger valves up to 6 inch pipe, cycle in about 1.5 seconds. A cycle is per 90° rotation

Q:Can I add a High Temperature kit to an existing Valworx air actuated?
A:Yes, you would need to select a kit matching both the actuator and valve mounting patterns. See actuator accessories

Q:Can I mechanically adjust the flow rate of an air actuated ball valve?
A: No, but we do offer pneumatic positioners with 4-20mA or 3-15PSI inputs. Positioners allow user to adjust flow 0-100%.

Q:Can I use the air actuated ball valve outside?
A: Yes, air actuated valves are weatherproof per materials of construction. Do not exceed minimum and maximum temperature specifications.

Q:Do you have a way to confirm the air actuated valve is in the closed position? Open position?
A: Yes, we offer an optional valve monitor/limit switch box. Monitor contains (2) dry contact limit switches used to confirm openand closed position. There is also a highly visual valve position indicator.

Q:What is the maximum allowable fluid velocity?
A:Metal valves: 5 to 10 feet/second, closer to 5ft/sec is better PVC valves: < 5 feet/second

Q:Can you customize the color of the actuator?
A: We can customize different colors, LOGO and so on according to customer's requirements.
