Equivalent pneumatic cylinders and valves (economy series)
Economical equivalents of cylinders and valves known in the industry by their series code: standard, round body, compact, mini, guided and hydro-pneumatic cylinders; 2V, 3V and 4V solenoid valves, mechanically operated valves.
A cylinder or valve on a machine is usually known by its series code. An economical equivalent of the same size gets the machine running without waiting and at lower cost. We find the equivalent that matches the mounting from the series code and dimensions of the old part and, where needed, recommend it in comparison with Pemaks products. We ship equivalent series products from stock anywhere in Türkiye and abroad, and also sell them through our online store hidroticaret.com (Turkish).
Types
SI series standard cylinders
Profile body standard cylinders with ISO 15552 mounting dimensions for medium and high force tasks.
DNC series standard cylinders
Profile body standard cylinders with ISO 15552 mounting dimensions. They fit directly in place of cylinders of the same size.
SC and SU series cylinders
SC is a tie rod standard cylinder and SU is a round-line profile body cylinder. General automation tasks.
MB series cylinders
Standard cylinders with a wide choice of bores and strokes. Aluminum body, stainless steel rod.
MA and MI series round body cylinders
Small bore round body cylinders with ISO 6432 mounting dimensions. Light pushing and positioning.
CQ2 and SDA series compact cylinders
Short body compact cylinders for places where a short stroke is needed in a tight space.
CU series mini cylinders
Rectangular body mini cylinders that mount directly through the body. Very tight mounting spaces.
MGP, TN and CXSM series guided and twin rod cylinders
Cylinders with two parallel rods or guide rods. They resist side load and rotation and carry the load directly.
Hydro-pneumatic cylinders
Cylinders that run on compressed air and boost force with hydraulic oil. High-force, short-stroke tasks such as pressing, riveting and punching.
2V series fluid valves
2/2-way solenoid valves that open and close the fluid line. For air and water lines.
3V series solenoid valves
3/2-way electrically operated valves. Single acting cylinders and air pilot control.
4V series solenoid valves
5/2 and 5/3-way electrically operated valves. They change the direction of double acting cylinders.
Mechanically operated valves
Roller, plunger, push button and lever valves. Position sensing and manual control.
How to select
An equivalent is an economical counterpart that matches the mounting dimensions and operating principle of the product known by the same series code. In selection the series code is a starting point. What really has to match is the bore, stroke, port thread, mounting dimensions and rod end thread. If these match, the equivalent fits in place of the old part without any change to the machine.
Replacement is easiest with standardized products: ISO 15552 profile cylinders and ISO 6432 round body cylinders have the same mounting dimensions regardless of brand. With compact, mini and guided cylinders the dimensions vary by series, and the dimensions of the old part are compared one by one.
When selecting an equivalent valve, the port thread, the number of ports and positions (2/2, 3/2, 5/2, 5/3), the coil voltage and the flow rate are checked together. We recommend the branded product on lines that run continuously and intensively or where long life is required, and the equivalent where an economical solution is wanted. The decision is made according to the application.
Product type by series code
| Series code | Product type | Note |
|---|---|---|
| SI, DNC | Standard profile body cylinder | ISO 15552 mounting dimensions |
| SC, SU | Standard cylinder | SC tie rod, SU profile body |
| MB | Standard cylinder | Wide choice of bores and strokes |
| MA, MI | Round body cylinder | ISO 6432 mounting dimensions |
| CQ2, SDA | Compact cylinder | Short body; dimensions vary by series |
| CU | Mini cylinder | Direct mounting through the body |
| MGP, TN, CXSM | Guided and twin rod cylinder | Resists side load and rotation |
| 2V | 2/2 solenoid valve | Opens and closes the fluid line |
| 3V | 3/2 solenoid valve | Single acting cylinder, air pilot |
| 4V | 5/2 and 5/3 solenoid valve | Double acting cylinder |
Series codes are the designations commonly used in the industry. In selecting an equivalent it is the dimensions that count, not the code: the dimensions of the old part are compared.
Frequently asked questions
Does an equivalent product fit in place of the original?
Yes, if the mounting dimensions, bore, stroke and thread match. Replacement is easiest with standardized cylinders (ISO 15552, ISO 6432). With the others, the dimensions are compared one by one.
Should I choose an equivalent or a branded product?
An equivalent is suitable where an economical solution and fast replacement are wanted. On lines that run continuously and intensively, or where long life is required, we recommend the branded product. The decision is made according to the application.
How do you find an equivalent for an old part?
The series code, bore, stroke and mounting dimensions, or a photo of the part, are enough. We compare the dimensions and recommend the one that fits.
What is the difference between a 4V and a 3V valve?
The 3V series is a 3/2-way valve, used for a single acting cylinder or for pilot air. The 4V series is a 5/2 or 5/3-way valve that controls both directions of a double acting cylinder.
When do I need a hydro-pneumatic cylinder?
When high force over a short stroke is needed on a machine that runs on compressed air: in tasks such as pressing, riveting and punching it provides the force without installing a hydraulic power unit.
