Standard Valves

SERİES: UL,SK,EK,UK

Standard valves are rotational control valves recommended for basic pneumatic applications. High and low temperature, atex applications, on-board and industrial applications are available.

	SERIES	DESCRIPTION
	UL	The direct acting solenoid valves series “UL” are produced in the 3/2 N.O. (with feed from the exhaust “3”) and 3/2 N.C. pneumatic functions. The function 2/2 is obtainable closing exhaust “3”. Besides are available the versions with ports G 1/8, suitable for single use, and with interface for multi-station base mounting or for mounting on poppet and to ex CETOP RP 32 P (with fixed position) valve bodies. They can comply with ATEX directive, 3GD category, upon request
	SK	Valves series “SK” are produced the size G1/8 in the following pneumatic functions: 3/2, 5/2, 5/3 and “3/2+3/2”. The electrical version can mount two kinds of piloting solenoid valves: the 15 mm one (type “SK815”) or the 22 mm integrated one (type “SK822”). Valves series “SK” can be used single or in manifold mounting, regardless the pneumatic functions: 5/3, 5/2 and 3/2, the last one using the adapter type “KIT/A/SK8”. The version “3/2+3/2” includes No. 2-3/2 valves in a single body, so with a very compact overall dimensions compared to the No. 2 valves it’s replacing in terms of pneumatic function, as well as compared to the pressure or open center versions. Upon request, they can be supplied in compliance with ATEX directive, category 3GD for electrical version with 15mm piloting solenoid valve and category 2GD for other versions.
	EK	Valves series “EK” are produced in the 3/2, 5/2 and 5/3 pneumatic functions; the kind of construction is based on a balanced spool. In the mechanically actuated version these valves are available only for the size G 1/8 and G 1/4, while the manually actuated versions are available in the different sizes and they are suitable for panel mounting (except for size G 1/2). They are in compliance with ATEX directive, 2GD category, upon request.
	UK	Valves series “UK” are produced in the 2/2, 3/2 and 5/2 monostable pneumatic functions. In the 3 port solenoid control version with small pilot system, sizes G 1/8 and G 1/4, support the 15 mm direct acting solenoid valve (type UMCSV with fixed position). All the other electric versions can support the 32 mm direct acting solenoid valve, type ULCSV/R (with fixed position), type C/USCSVG with sleeve Ø 9 mm (with fixed position and rotatable coils series USB and USBG) or the amplifier valve XVF4 for a sensible pneumatic piloting (see page 3.37). The 3/2 N.C. pilot actuated valves can also be used to switch vacuum thanks to a suitably reinforced spring. The poppet design assures high flow and high life. This series of valves, in the sizes G 1/8, G 1/4 and G 1/2, is prearranged for base mounting with conveyed inlet by means of rear notch screws. Upon request they comply with ATEX directive: 2GD category for pilot and solenoid actuated valves with coil type “USBG2” and 3GD category for the solenoid actuated valves with other coils type.
