ISO9001 Manufactured Solenoid Valves.

ISO 9001 certified solenoid valves are highly quality conscious and take every initiative to meet and exceed the international quality standards. To ensure the supreme quality finishing in our solenoid valve products, only premium quality raw materials from renowned and reliable company of the industry are used. Stringent quality tests and implementation to rigid quality control techniques at every stage of production ensure flawless solenoid valves. All solenoid valves are PED, ATEX, CE, CCOE, SIL, CMRI, UL (in process of approval) approved and this certifies that they are high on every quality parameters, thereby, deliver best in terms of performance and durability. Rotex solenoid valve products pass through a strict regimen of quality and capability tests in-house, including: High pressure Test (up to 400 bar gas), Hydrostatic Test (up to 700 bar), Mass spectro-Leak Detection Test (Up to 10-12 cc/sec), Cv test, Response Time and Time Characteristic Measurement Test and Life cycle Monitoring, Environmental Temp testing (in Environmental Chamber). Also all basic testing for Solenoid Valves and Pneumatic Actuators are done on PLC base Automatic Testing bench removing a complete human interference and thus providing error less supply. All products are tested for operation and performance as per the test plans drawn from prevailing industry standards (domestic and International). Specialised tests to check design integrity and satisfy performance criteria are outsourced, as and when required. Rotex solenoid valves offer total tractability and back-up support for its products, assuring the customer complete peace of mind.
