Stainless steel large diameter commonly used standard stainless steel flanged ball valve for Aniline movable top skid-mounted

The pneumatic two-stage control valve provides a three-position operation mode of 0°-45°-90° or 0°-90°-180°. The middle position is achieved by the movement of two auxiliary pistons to generate a mechanical brake. This middle position is adjustable, such as the 900 stroke actuator can provide 20°, 30°, 50°, 75° and other intermediate positions.

1.It can realize multi-position action control functions such as opening and closing of the valve for two sections, opening of the second section of the second section, and opening of the third section of the third section.
2.The speed of the on-off valve is adjustable;
3.The valve is opened and the valve opening degree is adjustable;
4.Automatic and manual control;
5.Safe return (FC/FO) for gas shutoff/de-energization;
6.Meet APl607 fire protection, APl6D anti-static requirements

Solenoid valves S1, S2 use 2-position 5-way solenoid valve, position as above
NSS1: 220VA or 24VDC relay output contact control S1
NSS2: 220VA or 24VDC relay output contact control S2
