Our counter balance hydraulic valves are used with a single acting or and double acting hydraulic cylinder.

COUNTER BALANCE VALVES

Used for both single- and double-acting hydraulic cylinders, these valves provide positive holding and controlled ‘chatter-free’ lowering of loads. The valve includes 2 male and female couplers, 2 hydraulic hoses, hydraulic fittings and dust caps. (The valve can also be supplied without these additional components, as you require).

This control valve is used to protect the hydraulic system from surges

METERING VALVES

Power Team metering valves have an in-line automatic design for systems using large cylinders or extended lengths of hydraulic hose. They can be used with both single- and double-acting hydraulic cylinders. The metering valve provides automatic surge control when the flow exceeds 26 l/min.

This hydraulic valve with solenoid control is used in a wide range of industry applications. This solenoid valve is renowned for reliability.

PILOT OPERATED CHECK VALVE

Suited for use with open or tandem centre hydraulic valves, these robust valves optimise free single-direction flow of hydraulic fluid. The valve is designed so that fluid flow is blocked in the opposite direction until pilot oil pressure is applied. In so doing, loss of hydraulic pressure is prevented should the valve be shifted or the pump line is broken.

This hydraulic check valve is a one way valve for unidirectional hydraulic fluid flow.

ONE-WAY CHECK VALVES

Our one-way hydraulic check valves utilise a rugged design for unidirectional flow of hydraulic fluid in your hydraulic system. The valve is fitted directly in your hydraulic line. It is designed for single-acting cylinder applications.

One of our hydraulic control valve solutions, the pressure reducing valve is designed for various applications requiring a reliable and robust pressure control valve.

PRESSURE REDUCING VALVE

These in-line automatic valves are designed for independent pressure control to 2 or more clamping systems operated by a single hydraulic power source. The high-quality design of this pressure control valve range allows operators to control a single continuous pressure source to supply various pressures in different stages of a single system.

This is hydraulic valve pressure control at its finest! This hydraulic control valve with flow control is an industry favourite.

PRESSURE REGULATOR VALVES

These are a reliable, high-quality pressure safety valve solution for adjusting operating pressure at various values below a pump’s relief valve setting.

It is easily adjusted to maintain pressures between 20 and 700 bar, with a flow range of 0.31 to 23 l/min, and can be used with single- or double-acting cylinders.

A pressure release valve is critical to your overall hydraulic system health. Ensure your hydraulic system operates within your required parameters with this flow control valve.

PRESSURE RELIEF VALVE

Ideal for remote locations in a hydraulic circuit, where maximum pressure requirements are less than basic overload valve settings in a pump. The in-line hydraulic pressure relief valve is adjustable from 70 to 700 bar and can be used with both single- or double-acting cylinders.

This pressure valve prevents against damage caused by excessive hydraulic pressure. The hydraulic overpressure valve range is designed for flow rates up to 19 l/min

RELIEF VALVES

Relief valves are a critical part in the health and safety of your hydraulic system and prevent potential machine damage, protecting the circuit from over-pressurisation. Our hydraulic overpressure valve range includes in-line automatic relief valves designed for a maximum flow rate of 19 l/min.

Achieve independent hydraulic valve positions with our sequencing hydraulic valves. Use with hydraulic valve multipliers.

SEQUENCE VALVES

These in-line automatic valves provide precise cylinder sequencing functionality in multi-cylinder hydraulic applications. A simple operation for ease of use – the pump is connected to one port and separate cylinders to another two ports. When pressure is applied to the pump-connected port, the first cylinder port advances and the other will not advance until a pre-determined pressure level in the cylinder is reached.

LOAD LOWERING VALVES

Designed for precision metering for controlled cylinder piston return, these in-line manual valves permit free-flow until the operator can open a locked valve.

The load lowering valve can be pre-set for a constant measured return, or the rate of return can be operator selected with each actuation. It has an operating pressure of 700 bar and 19 l/min.

This 3 way valve (or three way valve) is ideal for a wide range of hydraulic cylinders. It is a solenoid valve.

3-WAY 4-POSITION MANUAL PRESSURE COMPENSATED VALVES

These 3-way 4-position manual pressure compensated valves are designed for use with single-acting cylinders. The cylinder piston delivers relatively constant flow regardless of pressure between 69 and 689 bar.

more

 

 
This hydraulic valve is air operated. This air valve achieves flow up to 19 l/min at 700 bar.

AIR HYDRAULIC PUMP MOUNTED VALVES

Monitor pressure, loads, check valves for oil and flow metering with this air-actuated valve. Mount them directly mounted onto hydraulic pumps to provide precise performance measurement and hydraulic control. Our air-actuated valve provides up to 700 bar with maximum flow of 19 l/min. Standard 9.5 mm (3/8”) ports make these valves suited for simple mounting on a wide range of hydraulic pumps.

hydraulic valve basics

how to repair hydraulic valves

Power Team South Africa delivers full hydraulic valve repair services in Southern Africa. Our expert service crews will begin by disassembling your hydraulic valve and inspecting each element of its construction, replacing any worn or damaged components drawing on a large stock of hydraulic valve components before the hydraulic valve rebuild. Before you get your repaired valve back, it would have gone through a series of stress and strength tests to ensure it performs at the level it’s engineered to.

how hydraulic pressure relief valve works

In the event of a component failure in your hydraulic system, pressure can rapidly build to a dangerous level that, if left unchecked, quickly becomes hazardous. To prevent this from occurring, a hydraulic relief valve is installed in the circuit. When that pressure threshold is crossed, the hydraulic fluid is either diverted back to the hydraulic reservoir, or released from the sealed system. Read about our relief valves here.

 

how hydraulic pressure reducing valve works

Pressure reducing valves throttle the flow of hydraulic fluid to the pressure requirements of downstream hydraulic components. When these downstream components generate a certain pressure level, a pressure drop is created across main spool of the reducing valve that establishes the desired working pressure. The desired pressure is maintained by this continuously adjusting spool.

hydraulic valve vs pneumatic valve

Hydraulics is the fluid power system of choice in heavy-duty industrial maintenance equipment and tools, offering far greater potential force, much more efficiently, than pneumatic systems. Hydraulics offers precise and smooth moving and lifting of heavy loads. Pneumatic and hydraulic systems both use valves to control the force and velocity of the systems’ actuators.
