Descripci\u00f3n del producto<\/h2>\n

This pneumatic UPVC ball valve pairs a double-union UPVC valve with a rack-and-pinion air actuator for automated on\/off duty on aggressive chemical lines. UPVC handles acids, alkalis, seawater and other solutions that corrode stainless steel, and a quarter turn of the actuator opens or closes the line on a signal from your PLC or solenoid.<\/p>\n

The double-union (true union) body unscrews at both ends, so the valve drops out of the line for cleaning or seat replacement without cutting the pipe. Seats and O-rings are EPDM or FKM (Viton), sizes 1\/2\u2033 to 2\u2033. For metal lines, see our 316 stainless pneumatic ball valve<\/a>, o ver todos v\u00e1lvulas de bola neum\u00e1ticas<\/a>.<\/p>\n
