清管阀(亦称PIG 阀);清管阀是一种作为清管器(清管球、皮碗清管器、泡沫清管器等)发射或接收装置的新型阀门，它同时也具有通用两位式截断球阀的功能。它广泛应用于石油、化工、燃气、输水、印染、食品等领域，是对管道进行施工、清洁、保养维护、检测及管理必不可少的专用设备，使用清管阀并配合相应的清管器，可以更轻松地完成管道清洁、排空、隔离和按序输送介质等工作。清管阀能够完全替代传统使用的以清管器收发筒为核心的复杂的清管器发射、接受装置。
C型是标准型PIG阀。它的球孔通道面积比管通内径过流面积约大25%，以保证清管器到位后(即停留在接收阀内时)输送介质少量持续流动。
B型是一种带旁通的PIG阀，在球体上垂直于球孔方向开设两个椭圆形通道，其通流面积约为管子横截面积的25% 。这种结构保证即便在发射或接收清管器时PIC阀也不会发生断流。B型PIG阀不能当作截断阀使用。
S型主要是隔离输送介质用PIG阀。它的球孔面积比管子通流面积约大3%;并且在接收PIG阀的球孔内有一个附加密封，保证隔离清管器到达接收PIG阀时形成密封，获得理想的隔离效果。更重要的是它能实现清管过程中对内浮顶罐浮盘的保护功能，从而避免安全隐患。

Pigging valve (also known as PIG valve); pigging valve is a new type of valve, which is a launching or receiving device for pigging (pigging ball, leather bowl cleaner, foam pig, etc.). It also has the blocking function same as common used trunnion ball valve. It is widely used in the fields of petroleum, chemical industry, gas, water delivery, printing and dyeing, food, etc. it is essential special equipment for the construction, cleaning, maintenance, detection and management of pipelines. With the use of pigging valve and corresponding pigging device, it can more easily complete the work of pipeline cleaning, emptying, isolation and orderly transmission of media. The pig valve can completely replace the complex pig launcher and receiver which are used in the traditional way.
Type C is a standard pig valve. The ball hole is about 25% larger than the flow port of the pipeline, so as to ensure a small amount of continuous flow of the conveying medium after the pig is in place (when the pig stays in the receiving valve).
Type B is a pig valve with bypass. Two elliptical channels are arranged on the ball body perpendicular to the ball hole direction, and the flow passage is about 25% of the cross-sectional area of the pipeline. This structure ensures that the pig valve will not block the flow even when launching or receiving the pig. Type B pig valve cannot be used as a block valve.
Type S pig valve is mainly used to isolate the transmission medium. Its sphere hole area is about 3% larger than the pipe flow area, and there is an additional seal in the sphere hole of the receiving pig valve to ensure that the seal is formed when the isolation pig reaches the receiving pig valve and the ideal isolation effect is obtained. What's more, it can protect the floating plate of inner floating roof tank during pigging, so as to avoid potential safety hazards.
