The inner hole of the valve body is honing with gold steel.
The hardened and grounded spool is polished / deburring.
These measures ensure that their roundness and precision geometry (the control edges are not worn or widened),
and proper sealing gaps ensure minimal leakage.
壓力沖擊造成的影響，在鑄造閥體長(zhǎng)時(shí)期使用之后有時(shí)能觀察到，
表現(xiàn)在外表上形成并變遷的細(xì)微裂紋，特別是當(dāng)運(yùn)行于全額許用壓力之下。
在本系列換向閥中，這種現(xiàn)象從一開頭就可完全避免。閥體內(nèi)孔用金鋼珩磨。
Casting materials (molded castings of zinc and aluminum) are used only for pressure-free
parts such as operating mechanism housings, spring covers, and bottom plates.
It is also possible to provide a manual manipulator housing for ductile iron,
especially when used in harsh conditions and in series with valves.
淬硬和磨削過的閥芯經(jīng)過拋光/去毛刺。
這些措施保證了其圓度和精度的幾何形狀（控制邊不致磨損或變寬），恰當(dāng)?shù)拿芊忾g隙確保泄漏小。
鑄造材料（鋅和鋁的模壓鑄件）只用于無壓零部件，如操縱機(jī)構(gòu)殼體，彈簧蓋，底板等。
也可提供球墨鑄鐵做的手動(dòng)操縱機(jī)構(gòu)殼體，特別在惡劣工況下以及閥串聯(lián)連接時(shí)使用。
概述
The impact of pressure shocks can sometimes be observed after a long period of use in the casting valve body,
A fine crack that forms and changes on the surface, especially when running under full allowable pressure.
In this series of directional control valve,
this phenomenon can be completely avoided from the beginning.
 滑閥式換向閥通常用于液壓油作介質(zhì)的液壓系統(tǒng)。
換向閥用于控制液流方向，從而控制執(zhí)行機(jī)構(gòu)（液壓缸或液壓馬達(dá)）的運(yùn)動(dòng)方向。
 Slip valve type valve is usually used for hydraulic oil as a hydraulic system.
The directional control valve is used to control the flow direction and control
he direction of movement of the actuator (hydraulic cylinder or hydraulic motor).
The directional control valve is designed as a single unit,
