Versa patented the Anti-Extrusion Principal which is an O-ring sealing arrangement we invented for our valves. O-ring seals offer great advantages in valve design. 它们使阀门坚固可靠,组装和维护简单. 因为有现成的标准和定制的o形环密封, there is a wide choice of sealing materials, which is all great news.

However, when O-rings are used as a dynamic seal sometimes the internal forces can cause the seal to move or jump. When this happens the seals can become extruded or “nipped” which leaves small defects on the seal material. Our Anti-Extrusion Principle offsets the disadvantages of using O-rings by using a patented sealing arrangement in our O-ring packed valves. Basically, Versa seats O-ring seals within the valve body or on the valve plunger so the flow of the media or the pressure differential through the valve helps seat the O-ring. This keeps the O-rings in place which reduces the risk of extrusion and thereby enhances valve performance and life.

Versa offers diverter and selector valves for this purpose. Versa的3/2阀门有1个入口,1个气缸端口和1个排气端口. 反向分流阀(也称为7通阀)有1个入口,和2个出口端口. Versa选择阀(也称为8通阀)有2个入口和1个出口. Flow direction is important in Versa’s V Series product line.

No. The technical requirements for hydraulic vs. water service valves are very different. 根据这些媒体的独特要求和特性,选择和设计各不相同. Please select valve for the service. Contact Versa’s friendly expert Technical Sales team who will quickly determine your needs and advise on the exact options you’ll need for either hydraulic or water service.

Force is required to shift a pilot or solenoid-pilot valve. The shifting force must overcome the opposing force (often a spring holding the valve in one position.阀门规格包括迫使阀门转换所需的最小力. The physical force achieved by a pneumatic valve is created when the pressurized media acts on the surface area of the pilot piston, creating force. The force is measured by the pressure (of the media) multiplied times the surface area on which the pressure is applied (F=P x A). The minimum pilot pressure is minimum amount of pressure required to create a force greater than the opposing force in the device, thus allowing the control device to function.

Expilot is a term used to describe a solenoid-pilot directional control valve utilizing an external pilot signal. A pilot signal, often referred to as the pilot pressure, 在主体先导阀中产生做功所需的力. 电磁先导阀利用内部或外部源的先导信号. 内部导频源利用主体介质作为导频信号的源. A valve that uses an external pilot source does not utilize the main body media rather requires a separate, external pressurized source for the pilot signal. An expilot design is common when the pressure of controlled media does not meet the minimum pressure requirement of the main valve or where the control media need to be separated from the main body media.

A solenoid-pilot directional control valve utilizes a combination of a direct acting solenoid and a pilot valve. The solenoid direct acting valve controls the flow of a pressured media going to the pilot valve. 加压的先导介质推动先导活塞,产生一个力(F=P xa). That force is used to move the plunger in the pilot valve. Flow control occurs via the configuration of the plunger. 移动柱塞的动作控制介质的流动. 电磁先导设计的优点是具有较高的流动能力, high reliability, low power consumption and simplicity of piping/installation as pilot lines are integral to the valve. 缺点是它需要最小的压力来移动柱塞.
