The following are just some of the features that have made Conant Controls Valves among the most reliable in the industry:
Not just a coating, but solid PTFE, used in the sleeve or rotor of the valve has natural, self lubricating properties and a low coefficient of friction. Therefore, there is no need for oil or grease. PTFE has lower friction than any other solid material including graphite and molybdenum disulfide, and its lubricity results in smoother movement and operation of the valve.
In operation, thin films of PTFE are transferred from the rotor to the mating surface (or vice versa) in the body of the valve until it is coated with PTFE. Thus, the condition becomes one of PTFE sliding against PTFE. After the initial break-in period, this produces a surface with extremely low wear and eliminates fretting and galling.
Valves are completely resistant to nearly all chemicals, gases, and solvents, such as strong caustics, sulfuric and hydrofluoric acids, aqua regia, and solvents, such as aliphatic and aromatic hydrocarbons, alcohols, esters, ketones, and ethers up to their boiling points.
Caution: Avoid excessive tightening.
Caution: Avoid installation of plastic valves using metal fittings. Over tightening will result in damage to valve body.
Caution: Valve is assembled under load at factory!! Do not disassemble!!
Problem | Cause | Solution |
---|---|---|
Rotation of handle requires excessive torque. |
The PTFE seat will cold flow if valve remains inactive raising operational torque. | Operational torque will reduce after initial break in period. |
Media leaks from valve when closed. | There is particulate in seating area. Valve is not in correct position. Seat has worn |
Flush valve. Reposition valve handle. Return to factory for repair/replacement |
Handle fails to engage | Loose screw Knurl has worn out on handle. |
Tighten screw holding handle. Replace handle. |
