Legislation and Compliance
RoHS Certificate of Compliance
EU Directives 2011/65/EU and 2015/863 restrict the use of the 10 substances below in the manufacture of specified types of electrical equipment.
Whilst this restriction does not legally apply to components, it is recognised that component “compliance” is relevant to many customers.
RS definition of RoHS Compliance:
- The product does not contain any of the restricted substances in concentrations and applications banned by the Directive,
- and for components, the product is capable of being worked on at the higher temperatures required by lead–free soldering
The restricted substances and maximum allowed concentrations in the homogenous material are, by weight:
| Substance | Concentration |
| Lead | 0.1% |
| Mercury | 0.1% |
| PBB (Polybrominated Biphenyls) | 0.1% |
| PBDE ( Polybrominated Diphenyl Ethers) | 0.1% |
| Hexavalent Chromium | 0.1% |
| Cadmium | 0.01% |
| DEHP (Bis (2-Ethylhexl) phthalate) | 0.1% |
| BBP (Benzyl butyl phthalate) | 0.1% |
| DBP (Dibutyl phthalate) | 0.1% |
| DIBP (Diisobutyl phthalate) | 0.1% |
The supplier of the item listed below has informed RS Components that the product is "RoHS Compliant".
RS Components has taken all reasonable steps to confirm this statement. Information relates only to products sold on or after the date of this certificate.

Product Details
Two-way Valves and Control Modules
Valves and control modules designed specifically to operate together, provide a valve opening which is proportional to the input signal and allows this to be correlated to the respective operating conditions.
2/2 Proportional Flow Valve - 2875 Series
Burkert proportional solenoid valves provide continuously adjustable and smooth control over the flow of fluid passing through them. Unlike conventional solenoid and process valves which offer only On or off control, Burkert 2875series process valves use PWM (pulse width modulation) to give you the ability to adjust the flow from 0 to 100 percent. Design features such as the frictionless installation of the valve plunger, for exceptionally accurate adjustment and the tight sealing elastomeric seat make this the ideal valve for demanding and high accuracy control.
