many kinds of type you can choose.

1, flow control valve

The flow control valve can adjust the fluid resistance of throttle gate to handle the liquid flow, and thereby control the operating speed of the hydraulic actuators, such as cylinder and motor. This product mainly consists of throttle, speed regulator, overflow throttle, and split-flow collector. In most cases, this device should be installed horizontally.

One of the applications of this product is to reduce the hydraulic pressure to limit and keep the water flow within the preset range. In this way, though the upper level’s pressure increases sharply, the down level’s flow will remain unchanged.

Features 
1. This flow control valve changed the traditional flow controlling ways that using a orifice plate to control the flow and changing the cross-sectional area to control the flow mechanically. It takes use of the pilot valve to reduce the hydraulic energy loss to the maximum extent. 
2. This product has excellent operation sensitivity, and long service life. It is stable and safe in performance.

2,electromagnetic valve

The electromagnetic valve is an industrial device that can guide the direction and control the flow of industrial liquid medium. It can work with different circuits to achieve the goal of controlling, and ensure the good control accuracy and sensitivity. This product has many types, and can play different parts in the whole control system, such as one-way leading type, safety type, direction control type, and speed control type.

Features
1. The electromagnetic valve can be adjusted to adapt to the liquid mediums with different viscosities, such as water, gas, and oil. The adjustable viscosity adaptability makes the maintenance, purchase and installation of this product much easier.
2. The opening and shutting time is adjustable, so the risk of being damaged by water hammer could be removed.
3. The opening degree of the product can be adjustable, and the maximum and minimum opening degrees can be preset. 
4. The device supports the wear compensation, which can prolong its service life.

3, throttling valve 

The throttling valve is a device that changes the cross-sectional area of tube, or adjusts the chock length to control the liquid flow. We could combine this product with a one-way limiter to get a one-way throttling valve. In the quantitative pump hydraulic system, we can combine the product with a overflow limiter to get three different throttling systems, referring to the inlet line, outlet line and bypass throttling systems. For your information, this product does not have the function of flow navigate feedback, so it can auto-compensate the flow rate shortage caused by changing load. We advice the customer to apply it in the occasions where there is not too many load changes and requirements for the flow rate.

Features 
1. This throttling valve has simple structure and low price, and can be maintained easily.
2. The control precision of this product is too low to meet the requirement of speed controlling.
3. The sealing face of this device is erodible, and can be used to block the liquid medium.

4 reversing valve

The reversing valve is a device that has too or more liquid outlet ports. It can fulfill the connection, blocking, and reversing of the liquid flow. This device depends on the outer driving force to turn the link arm, and then open the valve plates alternatively to let the liquid flow in. Due to the different positions of the valve plates, the liquid flows from the left inlet port to the downside outlet port, ever and again, the liquid flows from the right inlet port to the downside outlet port. In this way, the goal of changing the liquid flow direction regularly and periodically can be achieved.

This product is often used in petroleum and chemical industries, especially in the Ammonia manufacturing. E.g. this product can be used onto the lubricating oil pipeline of the thin oil pipeline system.

Features
1. This reversing valve has precise mechanical action, high degree automation, and stable performance. It needs the additional driving system and cooling system. 
2. This product can be made into valve-clack structure which is often used in the occasion where the liquid flow is small, and the operator can turn the hand wheel to fulfill the change the flow direction. The valve-clack structural type dose not need any auxiliary device.
