1. This valve adopts the three-eccentric sealing structure, and the seats and disc plates are nearly free of abrasion, and the sealing function is more and more tight.
2. The sealing ring choose stainless steel, has the dual advantages of metal hard seal and elastic sealing no matter in the case of low or high temperature, it has good sealing performance in both, corrosion resistance, long service life, etc.
3. The sealing surface of plate is covered with cobalt hard alloy, the sealing surface is corrosion-resistant,and the service life is long.
4. This valve has a two-way sealing function. It is not restricted by the media flow when installed, and it is not affected by the space position. It can be installed in any direction.

The matching actuator parameters are as follows:
FRYT Quarter Turn Electric actuator
FRYT actuator is the part-turn electric actuator product, which can be used for controlling and regulating valves. The on-off product is appropriate for the application With 60 times of startup per hour, The regulated product is appropriate for the application With 1,200 times of startup per hour. Moreover, the control is more accurate and the positioning is more precise, due to increasing the intelligent control unit. The output range of the torque is 50 Nm (37 Ibf ft) - 2,000 Nm (1,476 lbf ft).
