Introduction
The 2 piece ball valve small size, large diameter, switch easy and convenient, reliable seal.simple structure, easy maintenance, sealing surface and sphere often closed state, not easy to be medium erosion, can be applied to water, aas, steam, oil. nitric acid. acetic acid and other media.

Pneumatic Actuator

| Double acting | Air to open, air to close, air supply failure to keep the current position |
| Single Acting N/O | Air to open, interrupt air to close, air failure to close |
| Single Acting N/O | Air to close, interrupt air to open, air failure to open |
| Optional accessory | Reversing solenoid valve, limit switch box, air filter reducing valve, positioner, handle manual, lock up valve |

Technical Parameters

Maintenance

Tightening the seal between the valve and the actuator:
Remove the four bolts underneath the actuator. Separate the actuator from the valve.
Tighten the nut on the top of the valve body.
Place the actuator back on the valve and screw everything back into place.

Tightening the seals between the valve and the inlet/outlet ports:
Remove the torque bolts and check for any debris or damage to the gaskets.
Use a torque wrench or other consistent method of tightening the torque bolts to reconnect the inlet and outlet ports.

Pneumatic Actuator

Introduction

1.Operating media: Dry or lubricated air, or the non-corrosive gases. The maximum particle diameter must be less than 30 µm.

2.Air supply pressure: The minimum supply pressure is 2.5 Bar. The maximum supply pressure is 8 Bar.

3.Operating temperature:

Standard: -20°C ~ +80°C

Low temperature: -35°C ~ +80°C

High temperature: -15°C ~ +150°C

4.Travel adjustment: Have adjustment range of ±5° for the rotation at 0° and 90°.
