Deceleration Valves / Deceleration and Check Valves

These valves are available either with or without an integral check valve which allows free reverse flow. Flow rate
through the valve is regulated by the movement of the spool, which is operated by a cam. When the spool is
depressed, the flow is decreased in Normally Open type valves and increased in Normally Closed type valves. Their
principal use is to control the speed of actuators in machine tools and similar applications.

Deceleration Valves / Deceleration and Check Valves 317

These valves are the combination of flow control valve, a deceleration valve and
a check valve and used mainly for controlling rapid traverse and feed cycles
machine tools. Switching from rapid traverse to feed is made by a cam
operation, and fine feed control is accomplished by dial rotation regardless of
pressure and oil temperature variation. Rapid return is free of cam actuation.

Pressure Drop
The following characteristics are based on the following conditions: viscosity of the fluid: 35 mm2/s (164 SSU) and
Specific Gravity: 0.850

For any other viscosity, multiply the factors in the table below.

For any other specific gravity (G'), the pressure drop ( P') may be obtained
from the formula below.

P' = P (G'/G) where, P is a value on the following chart and G is 0.850.

MODULES

YUKEN's Modular Valves are stack type valves, and require no piping. They not only rationalise system build, but
they also meet the technical requirements for a variety of hydraulic systems. Stacking systems is a new era in
hydraulics.
The valves have standardized mounting surface conforming to ISO 4401 and optimum thickness for each size. Any
hydraulic circuits can be easily composed by stacking the valves with mounting bolts. The valves can be used
widely for hydraulic systems for various industries such as machine tools, special purpose machines, ships and steel
mill equipment.

Hydraulic Fluids

Fluid Types
Any type of hydraulic fluid listed in the table below can be used.

Petroleum Base Oils Use fluids equivalent to ISO VG 32 or VG 46.
Synthetic Fluids
Water-containing Fluids Use phosphate ester or polyol ester fluids. When phosphate ester fluid is used, prefix "F-" to the
model number because the special seals (fluororubber) are required to be used.

Use water-glycol fluid.

Note: For use with hydraulic fluids other than those listed above, please consult your Yuken representatives in advance.

Recommended Fluid Viscosity and Temperature
Use hydraulic fluids which satisfy the both recommended viscosity and oil temperatures given in the table below.

Instructions
Caution in the selection of valves and circuit designing
The selection of modular valves, to suit a particular function or hydraulic circuit, are made in exactly the same way
as conventional valves, taking into account of the flow and pressure of each valve to be used. In some cases, the
stacking system may be restricted, so please refer to the following instructions for stacking sequence. Please note,
that when designing a system using modular stacking valves, due consideration should be given to working space
for future maintenance.

Stacking sequence when using reducing valves (for "A" (Incorrect) (Correct)
or "B" line) and pilot operated check valves.

Because reducing valves are spool type, there is an internal

leakage. In the stacking sequence shown in the drawing left Solenoid Operated
Directional Valve
(incorrect), the cylinder moves due to leakage through the
Pilot Operated
pilot pressure line . Check Valve

Consequently, retaining the position of the cylinder using (for "A&B-Lines")

a pilot operated check valve becomes impossible. The Reducing Valve
(for "B-Line")
stacking sequence shown in the drawing right (correct) is

required in order to retain the cylinder position.

P TB A P TB A

Stacking sequence when using reducing valves (for "A" (Incorrect) (Correct)
or "B" line) and throttle and check valves (for metre-

In B to T flow in the drawing left (incorrect), pressure is

the reducing valve may perform a pressure reducing Throttle and

The pressure so generated acts to shut the pilot operated Solenoid Operated

check valve and eventually creates an open and shut

operation of the valve repeatedly which may cause the Throttle and

Solenoid Operated A P TB A
In the drawing left (incorrect), pressure is generated at Directional Valve
part (a load pressure and a back pressure from
Throttle and
throttle effect). For structual reasons of the brake valve, the Check Valve
load pressure and back pressure act to open the valve, (for "A&B-Lines",
therefore, the setting pressure should be more than the
pressure equal to the load pressure plus back pressure (Pa Metre-out)
+ Pb). If the setting pressure is less than Pa + Pb, the brake
valve acts and brakes the movement of the actuator in Brake Valve
operation, this eventually reduces the speed of the actuator.
On the contrary, if the setting pressure is more than Pa + P TB
Pb, shock may occur when braking the actuator since the
setting pressure is too high against the load pressure.
Therefore, the stacking sequence in the drawing right
(correct) is required in this combination.

The minimum adjustment pressure equals the value
obtained from the minimum adjustment pressure P TB A
characteristics plus the tank line back pressure of MBP-01
the next page. This back pressure should include
the value of the T-line pressure drop characteristics P TB A
of the valves stacked to the base plate side of the MBA-01
modular valve.

To make pressure adjustment, loosen the lock nut MBB-01
and turn the pressure adjustment screw clockwise
or anti-clockwise. For an increase of pressure, turn
the screw clockwise. Be sure to re-tighten the lock
nut firmly after making adjustment to the pressure.

In case of a small flow, the setting pressure may
become unstable. To avoid this, refer to the
minimum flow characteristic curve of the next
page and use the valve within a range as shown
with .
