螺纹插装阀是继管式、板式、叠加式、二通插装式之后的一种新型阀种元件。
产品具有体积小、重量轻、不漏油、系统组合可靠性强等显著特点，
广泛应用于冶金、机床、轻工机械、锻压机械、通用石化机械等各个工业领域。
螺纹插装阀类型
螺纹插装阀可以分为：
1.压力控制阀
* 溢流阀
* 顺序阀
* 减压阀
* 平衡阀
* 负载阀
2.方向控制阀
* 单向阀
* 液控单向阀
* 方向控制阀(Magnetic, Manual)
* 电磁阀 (2,3,4 way, 2,3 position)
3.流量控制阀
* 节流阀
* 分流集流阀
2.Cartridge Directional Control Valve
(This type will control which device the fluid will flow to. These valves are the primary devices used to sequence the motion of equipment. There are many different types of directional control valves.)
* Cartridge Check Valves
* Pilot-operated check Valves
* Direction Valve (Magnetic, Manual)
* Cartridge Solenoid Valve (2,3,4 way, 2,3 position)
3.Cartridge Flow Control Valve
(In the case of flow control, a distinction is made between those affected by viscosity and those unaffected. it unaffected by viscosity are termed orifices. Throttles constitute resistances in a hydraulic system.)
* Throttle Valve
* Distribution Valve or diverter valve
* Flow regulating Valve
* Electro- Cartridge directional, flow, and pressure controls,
* Specialty valves - such as shuttle valves and velocity fuses,proportional valve,restriction valve
[Custom valve packages]
A custom valve package include at least one cartridge valve in a manifold. Usually, the manifold is custom designed for a specific application or function. The valve package may contain some or all of the control valving for a hydraulic system. Custom-designed hydraulic valve packages offer many advantages in mobile and industrial equipment.
产品特性: 1.重量轻，尺寸紧凑
-Combining several functions into a single manifold may save valuable space and weight, often occupying only 10% to 20% as much volume as conventional line-mounted systems plumbed with fittings, hose, and tubing.
2.泄漏量少
-Because a valve package eliminates so many connections, system leakage potential is reduced drastically.
3.提高系统有效性
-Valve packages that eliminate interconnecting lines and fittings lead to higher overall system efficiencies
4. 使用方便，便于维护
-Being more compact, valve packages sometimes can be mounted where they are less susceptible to external damage.
-Cartridges usually can be removed and replaced quickly without disturbing any external plumbing.
5. 外形美观，价格经济
-A clean design will not affect performance, but a good-looking machine on the dealer's sales floor in a competitive market can be an advantage to the OEM.
-On many systems, the cost of a custom valve package ,can be equal to (or less than) that of a system with individually plumbed components.
