SITEMA機(jī)械閥門執(zhí)行器MVA性能優(yōu)勢
德國SITEMA機(jī)械閥門執(zhí)行器MVA
充分舒適的氣動(dòng)SITEMA夾頭確保鏈條的斷裂
當(dāng)必須確保負(fù)載防止懸掛裝置（例如鏈條）破裂時(shí)，許多客戶使用我們的機(jī)械安全捕手KRM。該裝置具有在懸掛裝置破裂后立即保持負(fù)載的優(yōu)點(diǎn)。檢測鏈條破裂的附加傳感器不是必需的。另一方面，不可能在沒有懸掛裝置破裂的情況下在用戶定義的位置激活KRM。為維護(hù)目的。
在這里，機(jī)械閥執(zhí)行器MVA來救援。它只是簡單地放在懸掛裝置和移動(dòng)的負(fù)載之間。一旦MVA檢測到懸架裝置破裂，其集成閥就會被切換。這立即釋放來自所連接的氣動(dòng)夾緊頭的壓力，并且負(fù)載被牢固地保持。 MVA和夾緊頭直接相互通信，無需通過應(yīng)用的控制系統(tǒng)，響應(yīng)時(shí)間非常快。
通過使用MVA，可通過釋放壓力在任何位置啟動(dòng)的氣動(dòng)夾具的優(yōu)點(diǎn)可與機(jī)械安全捕捉器KRM（檢測鏈條破裂，快速反應(yīng)時(shí)間）的優(yōu)點(diǎn)相結(jié)合。
獨(dú)立于懸掛裝置的破裂，使用過的氣動(dòng)夾頭可以通過第二個(gè)閥門正常控制，并覆蓋許多不同的其他情況（電機(jī)故障，緊急停止，防護(hù)門打開等）。
通常，我們所有的氣動(dòng)夾頭系列都可以用機(jī)械閥門執(zhí)行機(jī)構(gòu)來控制，例如，我們的氣動(dòng)安全捕捉器和我們的安全制動(dòng)器KSP。
機(jī)械閥門執(zhí)行器有兩種尺寸可供選擇（允許載荷zui大20 kN / 35 kN）。請與我們了解更多詳情。

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.
