Product Description
PC70 sectional hydraulic multi‑way valve is a heavy‑duty modular directional control valve designed for mobile machinery hydraulic systems, with nominal flow 70 L/min. It supports both open‑center and closed‑center circuit configuration. Modular sectional design allows 1‑8 working sections freely combined to meet multi‑function operation demands. Multiple actuation options are available: manual, pneumatic, electro‑pneumatic, hydraulic pilot and electro‑hydraulic control. Built‑in main relief valve and individual load check valves prevent load dropping, deliver stable and smooth operation for off‑road mobile equipment.
Modular sectional construction, flexible section quantity combination, easy modification and maintenance
Integrated main pressure relief valve and individual load check valve for each section, effectively avoid load slipping
Wide spool options: floating spool, regenerative spool, detent / kick‑out spool for different working requirements
Diversified actuation modes, adapt to manual onsite operation and remote automated control
Precision machined valve body and spool, low internal leakage, smooth spool shifting, low noise during operation
Compact overall dimension, high pressure resistance, long service life for harsh outdoor working conditions

1. What is the PC70 Control Valve ?
PC70 is a sectional multi‑way directional control valve engineered for mobile hydraulic machinery. With 70 L/min nominal flow, it can be assembled from 1 to 8 working sections according to customer requirements.
It supports open‑center and closed‑center hydraulic circuits. Multiple actuation choices are available: manual, pneumatic, electro‑pneumatic, hydraulic pilot and electro‑hydraulic control.
Built‑in main relief valve and individual load check valves prevent load drop‑off. It delivers stable performance under harsh outdoor working conditions, widely used on agricultural, construction, forestry and municipal mobile equipment.
2. What makes the PC70 Control Valve ?
Modular sectional design enables flexible combination from 1‑8 working sections, easy assembly, re‑configuration and field maintenance.
Supports both open‑center and closed‑center hydraulic circuits, compatible with diverse mobile system layouts.
Multiple actuation options including manual, pneumatic, electro‑pneumatic, hydraulic pilot and electro‑hydraulic control, covering onsite operation and remote automatic control demands.
Integrated main relief valve plus independent load check valves per section, effectively prevents load slipping and guarantees operation safety.
Wide range of spool configurations: floating, regenerative, detent and kick‑out spools for different working functions.
Precision‑machined valve body and spool assembly, low internal leakage, smooth spool shifting and low operating noise.
High pressure rating suitable for tough outdoor working environments, long service life for agriculture, construction, forestry and municipal machinery.
Optional power‑beyond port simplifies multi‑pump hydraulic system integration.
3. What is the working pressure range of PC70 Control Valve ?
Max inlet pressure (P‑port): 250 bar (3625 PSI) Max working pressure (A/B service ports): 300 bar (4350 PSI) Max back pressure (T‑tank port): 50 bar (725 PSI)
The built‑in main relief valve is field‑adjustable to set system working pressure within the safe pressure scope for mobile machinery hydraulic circuits.
4. Can PC70 Control Valve replace other brands?
PC70 sectional control valve can serve as a functional replacement for many mainstream 70 L/min sectional multi‑way valves for mobile machinery.
Direct drop‑in swap depends on mounting dimensions, port thread sizes, spool type, circuit configuration (open‑center / closed‑center) and actuation form. If these key parameters match, PC70 can replace equivalent valves from other brands.
Custom modification is available when original mounting or port layout differs. Please provide original valve model, port size, spool function and section quantity for compatibility confirmation before ordering.
It is not a direct OEM drop‑in replacement for excavator main control valves. It is designed for agricultural, construction, forestry and municipal mobile equipment.
5. What is the typical speed range of PC70 Control Valve ?
PC70 sectional valve does not define a fixed mechanical speed rating. Its operating performance depends on hydraulic flow supplied to the valve.
Recommended continuous operating flow: 0‑70 L/min Maximum intermittent flow: up to 85 L/min
Spool shifting speed is determined by pilot oil flow (for pilot‑operated versions) or manual lever movement. For manual version: shift speed relies on operator lever action. For hydraulic / electro‑hydraulic pilot version: typical spool response time ranges 80‑250 ms, subject to pilot pressure and pilot flow.
Exceeding 70 L/min continuous flow will increase pressure drop, internal heat generation and shorten service life.
