Product Advantage

Our valve has standard thickness according to GB26640, makes it capable of holding high pressure when needed.

Our valve seat use imported nature rubber, with more than 50% of rubber inside. The seat has a good elasticity property, with long service life. It can be open and close more than 10,000 times with no damage for the seat.

The valve seat with 3 bushing and 3 O ring, helps supporting the stem and guarantee the sealing.

The valve body use high adhesive force epoxy resin powder, helps it adhere to the body after melting.

Bolts and nuts use ss304 material, with higher rust protection capability.

Butterfly valve pin use modulation type, high strength, wear-resisting and safe connection.

E/P POSITIONER ex ia iic T6:

Ex ia

Ex: Indicates that the equipment is designed for use in explosive atmospheres.
ia: The highest level of intrinsic safety protection. It means that the device is designed to prevent any kind of sparks or heat that could ignite an explosive atmosphere, even under two fault conditions (e.g., device failure or external damage).
Equipment with the "ia" designation can be used in the most dangerous environments, where explosive gases are continuously present.

IIC

This part of the rating defines the gas group for which the equipment is certified. The gas groups range from IIA to IIC, with IIC being the most severe, covering the most dangerous gases.
IIC: Suitable for atmospheres containing hydrogen, acetylene, or similar explosive gases. These gases are the most easily ignitable, so the equipment needs to meet the highest protection standards.

T6

The T6 designation refers to the maximum surface temperature of the equipment under normal operating conditions, which is critical in explosive environments.
T6 means the surface temperature will not exceed 85°C (185°F), even in the worst-case scenario. This is the strictest temperature class, ensuring that the device is safe to use around even highly sensitive gases that could ignite at relatively low.
