由红阀发明并推出的气动A型管夹阀为流体控制问题提供了一个独特且性价比高的解决方案。在全球范围内，正在使用的红阀A型管夹阀数量超过了其他任何管夹阀，其秘密在于橡胶套管-管夹阀的唯一过流零件。阀门的驱动或夹紧动作，由作用在套管上的带压空气和液体完成。阀体作为一个内置的驱动装置，省去了昂贵的气动/液动/电动执行器。通过控制阀体和套管间的环形空间里的空气压力，我们可以开关或调解阀门。气源压力大约高于管线压力35psi,就可以使阀门关闭。
套管的弹性允许阀门在有残存颗粒时零泄漏关闭，避免了损坏阀门，密封区域相当于95%的阀门长度。没有阀座、密封填料需要更换，没有间隙和死角会滞留防碍阀门操作的碎块。A型管夹阀的抗磨损能力是无与伦比的，当阀门全开时，它就像管线中的一段管子一样。A型管夹阀用于不易到达的位置或环境恶劣中，因为阀门没有外部联结、手柄、活塞或旋转部件，从而不会因此带来故障停机。
控制：
使用一个升压器或比例继电器来调节A型管夹阀的空气压力，可以完全调流控制。通过改变比例继电器的信号气压也可调节A型管夹阀。

A型管夹阀的加厚套管：
针对高磨损工况设计，用于磨蚀性泥浆时，A型加厚套管管夹阀的使用寿命甚至优于斯太莱硬质合金V型球阀和其它金属密封阀门。为了补偿额外的套管厚度带来的流道缩小，阀体规格必须增大至下一个口径。

A型锥形套管管夹阀：
A型锥形套管管夹阀专为节流控制应用而设计，通过缩小套管中央的流道直径，阀门的Cv值可以满足任何要求，为了提高耐磨能力，流道下游，套管的后半部分，流道都是缩小的。而且，压力恢复发生在阀门的下游，气蚀也被降至最低。

A series pipe clamp valve
Features:
l Zero leakage close even there is remaining particles
l Full bore, thickening or tapered bushing type
l Simple design, not influenced by harsh external environment
l Body bears the functionality of inside drive device
l There is no need to change or maintain seal parts at any time
l There are no gaps and blind angles to prevent valve operation
Structure material
l Body: cast iron or aluminum
l Casing: natural rubber, neoprene, Hypalon, chloride, butyl rubber, nitrile rubber, EPDM and Viton
l Flange: ANSI125/150, 250/300 pound class
l The pneumatic type A pipe clamp valve that is invented and launched by Red Valve it provides a unique and cost-effective solution for flow controlling problem. On a global scale, the quantity of type A pipe clamp valves is more than any other pipe clamp valve, the secret is the only over-flow parts in the rubber casing pipe clamp valve. Valve’s drive or clamping is realized by compressed air and liquid which act on the casing pipe. It eliminates the need for expensive pneumatic/hydraulic/electric actuator as the body is as a built-in drive device. By controlling the air pressure in the annular space between valve body and casing pipe, we can switch or adjust valve. The valve can be closed if the air supply pressure is 35 psi higher than the pipeline.
l The casing pipe elasticity allows the zero leakage close even when there is remaining particles, in this way the valve can avoid being damaged. The sealing region is equivalent to 95% of the length of valve. There is no need for seat and seal filler to be replaced, there are no gaps and blind angles to prevent valve operation. Type a pipe clamp valve’s wear resistance is unmatched, when the valve is fully open, it’s like a section of pipe in the pipeline. Type A pipe clamp valve is used in the position of uneasy to reach or harsh environment, it will not cause stoppage because there is no external link s, valve handle, piston or rotating parts in the valve.
Control：
Use a booster or proportional relay to adjust the air pressure of the type A pipe clamp valve, it can fully adjust the control.
Thickening casing pipe of type A pipe clamp valve：
Designed for high wear conditions, when used for abrasive slurry, type A thickening casing pipe clamp valve life time is even longer than Staline carbide v-ball valve and other metal seal valve. In order to improve the wear ability, the downstream flow channel and the latter part of casing pipe, the flow channel is narrowed.
A type tapered casing pipe clamp valve：
A type tapered casing pipe clamp valve is specifically designed for flow control application, by narrowing casing diameter of casing pipe center, the valve Cv value could meet any requirement. Meanwhile, the pressure recovery happens at the pipe downstream, the gas etching is minimized.
