FAQ
Pneumatic Valve 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 open and 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.
