充分舒适的气动厂滨罢贰惭础夹头确保链条的断裂
当必须确保负载防止悬挂装置（例如链条）破裂时，许多客户使用我们的机械安全捕手碍搁惭。该装置具有在悬挂装置破裂后立即保持负载的优点。检测链条破裂的附加传感器不是必需的。另一方面，不可能在没有悬挂装置破裂的情况下在用户定义的位置激活碍搁惭。为维护目的。
在这里，机械阀执行器MVA来救援。它只是简单地放在悬挂装置和移动的负载之间。一旦MVA检测到悬架装置破裂，其集成阀就会被切换。这立即释放来自所连接的气动夹紧头的压力，并且负载被牢固地保持。 MVA和夹紧头直接相互通信，无需通过应用的控制系统，响应时间非常快。
通过使用惭痴础，可通过释放压力在任何位置启动的气动夹具的优点可与机械安全捕捉器碍搁惭（检测链条破裂，快速反应时间）的优点相结合。
独立于悬挂装置的破裂，使用过的气动夹头可以通过第二个阀门正常控制，并覆盖许多不同的其他情况（电机故障，紧急停止，防护门打开等）。
通常，我们所有的气动夹头系列都可以用机械阀门执行机构来控制，例如，我们的气动安全捕捉器和我们的安全制动器碍厂笔。
机械阀门执行器有两种尺寸可供选择（允许载荷zui大20 kN / 35 kN）。请与我们了解更多详情。

Mechanical Valve Actuator MVA

Secure the rupture of a chain with the full comfort of a pneumatic SITEMA clamping head

When a load has to be secured against rupture of a suspension device (e.g. a chain), many customers use our Mechanical Safety Catcher KRM. This unit has the advantage to hold the load immediay upon rupture of the suspension device. Additional sensors to detect rupture of a chain are not necessary. On the other hand, it is not possible to activate the KRM in a user-defined position without rupture of the suspension device, e.g. for maintenance purposes.

Here, the Mechanical Valve Actuator MVA comes to your rescue. It is simply put between the suspension device and the moving load. As soon as the MVA detects rupture of the suspension device, its integrated valve is switched. This immediay releases the pressure from the connected pneumatic clamping head, and the load is securely held. MVA and clamping head communicate with each other directly, so there is no need to go via the application’s control system, and the response time is very fast.

By using the MVA, the advantages of a pneumatic clamp, which can be activated in any position by releasing the pressure, can be combined with the advantages of the Mechanical Safety Catcher KRM (detection of chain rupture, fast reaction time).

Independent of the rupture of the suspension device, the used pneumatic clamping head can be controlled normally via a second valve and cover many different other cases (motor failure, emergency stop, opening of a guard door, …).

Generally, all our pneumatic clamping head series can be controlled with the Mechanical Valve Actuator, e.g. our pneumatic Safety Catchers and our Safety Brakes KSP.

The Mechanical Valve Actuator is available in two sizes (admissible load up to 20 kN / up to 35 kN). Please contact us for more details.
