DCV series manual hydraulic directional control valve Advantages

- High-strength Casting: Graphite cast iron shell via precision shell molding, bigger inner flow channel, low pressure loss and less heat generation.
- Durable Spool: Precision ground nickel-plated spool with radial balance groove, smooth lever operation without jamming; single spool replaceable for easy maintenance.
- Rich Optional Functions: Optional individual overload relief valve and anti-cavitation valve on each working port; bypass oil port design to connect extra downstream hydraulic circuits.
Frequently Asked Questions(FAQ)
Q1: Monoblock vs Sectional DCV80, how to select?
A: Monoblock is integrated cast body, compact with fewer leakage points, fit fixed-spool loader/forklift(1~6 spools). Stackable sectional valve allows later spool addition/removal, more suitable for customized agricultural machinery.
Q2: Is separate port relief valve available?
A: Yes, single A/B port can be equipped with adjustable overload relief valve(100~315bar preset). Anti-cavitation check valve is optional for anti-overrunning cylinder damage.
Q3: Stiff spool after long-term use?
A: Oil contamination causes spool blocking normally. Nickel-plated spool can be cleaned or replaced separately without whole valve replacement; PTFE coated spool is optional for severe working conditions. Regular hydraulic oil & filter replacement effectively prolong service life.
Production & QC
Our factory is ISO9001:2015 certified. All valves pass strict inspection: raw material inspection → CNC precise machining(tolerance ≤0.008mm) → anti-rust & nickel surface treatment → full-offline bench test. Every finished product is tested on leakage and operating flexibility before delivery, internal leakage controlled below 25 drops/min under rated pressure.
