Electric valve actuator regulator type, passive contact switch type

A: Most likely the valve stem or actuator coupling is broken.

A: Remove the actuator from the valve and check the valve stem. Most ball valves have stem flats at right angles to the flow when the valve is in the off position. On butterfly valves check the stem flow arrow marking.

A: Check the electric wiring schematic that came with the actuator for the correct hookup. Sometimes a copy is inside the actuator cover. If it is missing, don't guess about the connections. Call us for a schematic.

A:We are professional manufacturer,specialized in VALVES for 18+ years.

A:Yes. We accept OEM based on considerable quantity

A: 20-30 days after deposit.Urgent order can be negotiable.

A:Absolutely! But we consider to receive small amount of sample fee as a sign of sincerely cooperation and will compensate it in products for your future order.

This material's chemical resistance are very similar to those of PVC. Its major advantage over PVC is the ability to handle hot
corrosive liquids in service temperatures up to 180°F (82°C).

It is a thermoplastic with low specific gravity and excellent chemical resistance to a wide range of acids, alkalies and organic
solvents. It is also used in deionized water distribution. It is not recommended for use with strong oxidizing acids, chlorinated
hydrocarbons and aromatics.

It is chemically resistant to most strong acids, mild alkalies, organic solvents, wet or dry chlorines, bromine and other halogens
and is also used extensively in the conveyance of high purity deionized water due to its absence of colorants or additives

This fluoroelastomer provides chemical resistance to a wide range of chemicals, concentrations and temperatures involving mineral
acids, salt solutions, chlorinated hydrocarbons and petroleum oils. Although its chemical compatibility to most acids is excellent
it can be mechanically swollen by some

This elastomer has good abrasion and tear resistance while offering excellent chemical resistance to a variety of acids,
alkalines, alcohols and oxidizing chemicals. However, it is susceptible to attack by oils.
