EPP part-turn electric actuator: EPP-1 800, EPP-2 500, EPP-6 000

EPP-1 800/2 500/6 000 explosion-proof partturn actuators with duplex torque limiting coupler are designed for operating DN 100...350 ball valves, PN up to 16.0 MPa, (with differential pressure at up to PN) in outdoor installations and in premises in explosive areas of class «1» and «2» according to GOST 30852.9-2002, where steamand gas-air explosive mixtures of category IIA, IIB, groups T1, T2, T3 and T4 as per GOST 30852.5-2002 and GOST 30852.11-2002 classifi cation could be formed.

Example of product code for ordering:

«EPP-1 800» F14.60.Т220(024).UKhL1-а(r) TU 3791-024-00139181-2007 Explosion-Proof Part-Turn Electric Actuator», where:

- «EPP» – is part-turn electric actuator;

- 1 800 (2 500, 6 000) – is the rated torque at the output element, Nm;

- F12, F14 (F16, F25) – is a mechanical interface as per ISO 5211-2001;

- 60 (100) – is the time of ball valve travel between Close/Open end points, sec;

- Т220 (Т024) – is the version of electronic control unit by interface signals;

- UKhL1 – is the climatic and placement category as per GOST 15150;

- а – is the type of explosion-proof cable entries for connection with external power circuits and alarm and control circuits in armoured cables;

 r – is the type of explosion-proof cable entries for connection with external power circuits and alarm and control circuits in unarmoured cables laid in stationary conduit or fl exible metallic hose.
