天榆液壓氣動(dòng)通過優(yōu)化閥體內(nèi)部流道設(shè)計(jì)，降低壓力損失，提升響應(yīng)速度。產(chǎn)品穩(wěn)定性高，在頻繁啟閉工況下仍能保持性能一致性。用戶可根據(jù)實(shí)際需求選擇MPCV-02B的不同變型型號(hào)（如MPCV-02A、MPCV-02W等），以適應(yīng)多樣化系統(tǒng)配置。1926
Product Introduction (English)
The MPCV-02B/MPCV02B is a stackable pilot-operated check valve manufactured by Tianyu Hydraulic & Pneumatic, designed to regulate unidirectional oil flow in hydraulic systems while allowing reverse flow when external pilot pressure is applied. Its compact stacked structure enables easy integration with other hydraulic valves, reducing piping complexity and enhancing system reliability. 1226
Key Features
This valve features a robust cast iron construction and soft sealing mechanism, suitable for medium-to-high pressure applications (up to 24MPa). It supports diverse hydraulic fluids including petroleum-based oils, synthetic fluids, and water-glycol mixtures within a viscosity range of 15-400cSt. The bidirectional control capability ensures efficient pressure maintenance and rapid exhaust in circuits. 2819
Technical Specifications
With a nominal bore of 10mm and unidirectional flow design, the MPCV-02B operates optimally between -15°C and +70°C. For prolonged service life, it is recommended to maintain fluid cleanliness (NAS1638-12 standard) using 25μm filtration. The valve’s modular installation simplifies maintenance and system upgrades. 1226
Applications
Ideal for industrial machinery such as injection molding machines, presses, and construction equipment, this valve excels in scenarios requiring load-holding, fast cylinder retraction, or vacuum prevention in vertical cylinders. Its performance ensures stability under cyclic operations. 2829
Advantages
Tianyu’s engineering refinements in internal flow paths minimize pressure drops and improve response times. The MPCV-02B series offers variant models (e.g., MPCV-02A/W) to accommodate customized hydraulic configurations, delivering consistent performance across diverse operating conditions. 1926
