DIN Double Acting Pneumatic Valve , PN16 Pneumatic Control Valve

DIN Double Acting 2 Way Stainless Steel Pneumatic Valves DN50 Flange Ends

Description

This pneumatically controlled 2-way ball valve allows for an increase in automation to your system compared to a manually controlled valve. The ball valve has a 100 mm diameter and is suitable for liquids and gases from -20 to 180°C. The pneumatic actuator is capable of creating 354 Nm of torque at 8 bar, but it has a control pressure window of 6 ? 10 bar. The ball valve has G 4" threads to connect it to the piping/hosing carrying the media and the Kv value is 1230 m3. The actuator is double acting with a reliable aluminium rack-and-pinion rotational operation. The actuator has an anodized aluminum housing and an aluminum cover, while the ball valve has a stainless steel housing and a PTFE seal. The maximum media pressure is 63 bar. The ball valve is a 3-piece design allowing for thorough cleaning. Namur VDI/VDE 3845 connection points are already on the actuator to mount a 1/4" Namur solenoid valve directly onto the actuator or connect an air hose utilizing the G 1/4". Also, a position control or limit switch box can be mounted on the top of the actuator according to VDI/VDE 3845. The actuator is mounted on the ball valve via the ISO 5211 F10 flange (22 mm). The assembly is ATEX certified (EX II 2GD c) and may therefore be used in potentially explosive environments.Pros:Ability to directly mount a Namur solenoid valve to reduce fittings and tubing.Mechanical indicator on top shows the valve position.ATEX (EX II 2GD c) certified for explosive environments.Lower investment cost than an electric version.Fast opening/closingDouble acting allows for greater control than single acting actuators. The ball valve is a 3-piece design allowing for thorough cleaning.Can be equipped with a limit switch box.Cons:Double acting utilizes more compressed air than single acting actuators. It requires a compressed air system and a solenoid valve to control the air supply.
