VARIABLE AXIAL-PISTON PUMPS FOR OPEN CIRCUITS WITH LS
CONTROL (Series C)
- Variable displacement axial-piston pump is used in open
circuits. Pump is applied at tractors, agricultural, mobile machines and
other equipment in temperate and tropical climate.Pump control is realized
by supply and pressure adjuster, which limits maximum pressure level in
pressure line and keeps pump supply at preset level regardless of load and
speed. Axial-piston pump is easily controlled and relatively compact.

control (Series C1)
- Variable displacement axial-piston pumps Series C1 are
used in open circuits. Pumps are applied at tractors, agricultural and

Control valves
- Control valves are the components of hydraulic system,
the main assignment of which is to control the flow in the hydraulic lines.
Spool valves. In the spool type valves the flow direction is fulfilled by
means of axial shift of spool control element. Hydrosila manufactures two
types of control valves: monoblock and modular control valves.
Monoblock control valves have classic effective design. All the
spools are installed in one body and it gives the opportunity to refine the
size and the weight of the control valve for the separate kind of machine.
Modular control valves have several cells, what gives the opportunity
to use the valve for control of hydraulic system with different actuators.
The main advantage of the modular control valve – when using the valve only
the separate section may be changed if it’s out of order.
Monoblock control valves

- Proportional pneumatic tipping valve with open center
MR100.T1 suitable for medium- and heavy-duty trucks.

that allows to operate trucks with a dump trailer.
Sectional control valves

- The valves are used to change the fluid flow and protect hydraulic systems of tractors, agricultural, construction and other mobile machines against overloads.

MRS120.B1
- Directional control valves MRS120 series are universal
control valves of a wide application. MRS120 series control valves are
intended for use on excavators, cranes, loaders, trucks, drilling machines

Hydraulic cylinders
Piston-type / Plunger-type

Piston-type - MC-series hydraulic cilinders
- Piston double-acting hydraulic cylinders. Used in
agricultural, road construction, utility machines and other equipment.

Plunger-type - MCP-series hydraulic cilinders
- Plunger single-action hydraulic cilinders. Used in
agricultural, road construction, utility machines and equipment.
Quick release couplings
- Quick-release couplings are available in various sizes
(from 1/4 "to 1") with interchangeability of the contact part of the socket
and nipple according to ISO 7241-A, ISO 14541, ISO 16028 ("Flat Face").
Quick-release couplings can be manufactured with various types of fittings
with metric and inch threads.
1. The couplings are made on high-precision equipment made of carbon steel
with high-quality external and internal galvanic zinc coating, which ensures
their hermetic connection and long service life with repeated
connection-disconnection, as well as the necessary corrosion resistance.
2. The O-ring is made of high-strength rubber based on oil-and-petrol
resistant rubber, which ensures optimum tightness of the coupling coupling
and long service life of the quick-release coupling.
3. The shut-off valve in both coupling halves automatically shut off the
flow of working fluid during disconnection and is made in a conical shape,
which ensures full opening and closing of these valves.
4. The diameter of the inner working chamber allows the working fluid to
work in the optimal temperature regime without overheating, without
hindering the operation of the hydraulic connections.
5. The connecting dimensions of both coupling halves correspond to the ISO
7241-A standard, which makes it possible to use the "HYROSILA" coupling
half-couplings with the coupling halves of the world manufacturers of the
same size.
6. The valve base in both coupling halves is made of a high-strength alloy,
which increases the life of the quick-release coupling.
7. Fittings are connected to the main part of the coupling half by threaded
connection through a sealing rubber ring, which ensures tightness and a long
service life. 
Quick release couplings "QR"
- Interchangeability according to ISO 7241-series A. Ball
clamping of half couplings. Poppet valve. Two-way "connection-disconnection"
(the so-called "breakaway function" or "Push-pull" connection). Connection
by pushing the male coupling. Disconnection by pulling the male part.
Connectable with male part (ISO A) under pressure. Most often found on
agricultural and communal machinery. Designed for light operating
conditions, as well as where there are no ultra-high pressures.

Quick release couplings "QS"
- Interchangeability according to ISO 7241-series A. Ball
clamping of half couplings. Poppet valve. One-way
"connection-disconnection". Most often found on agricultural and communal
machinery. Designed for light operating conditions, as well as where there
are no ultra-high pressures.

Quick release coupling "QT"
- Interchangeability according to ISO 14541. Threaded
locking half couplings. Poppet valve. They are used for high, as well as
pulse pressure. It is most often used on agricultural, construction and road
machinery, and machinery working in quarries.

Quick release coupling "QF"
- Interchangeability according to ISO 16028. Ball clamping
of half couplings. The valve is a flat face ("flat face"). The presence of a
lock to prevent spontaneous detachment. Used in hydraulic systems, where it
is necessary to eliminate the possibility of external oil leaks and there is
a risk of contamination of the liquid. This type of connection allows you to
successfully work with impulse loads such as a hammer.
