1 efore using the product, please check the Pressure ontrol Valves JIS graphic symbols for hydraulic system Refer to the next page. Features These direct operated control valves can be used as sequence valves, unload valves, counter balance valves, or relief valves by changing the combination of internal and external pilot and drain settings Nomenclature - JQ pplicable fluid code No designation: Petroleum-based hydraulic fluid, water-glycol hydraulic fluid F: Phosphate ester hydraulic fluid Model No. JQ: JQ type control valve heck valve code No designation: Without check valve : With check valve onnections G: Gasket mount type T: Screw connection type F: Flange connection type Nominal diameter 3: ⅜ : ¾ 1: 1¼ 1: Function code (See JIS graphic symbols for hydraulic system)* 1 : Sequence valve (internal pilot type, external drain type) <With no option code designation> ounter balance valve (internal/external pilot type, external drain type) <With W option code designation> Pressure adjustment range : 5 to.85 MPa {.5 to 8.5 kgf/cm } :.85 to 3.5 MPa {8.5 to 35 kgf/cm } : 3.5 to 1 MPa {35 to 1 kgf/cm } : 1.75 to 7 MPa {17.5 to 7 kgf/cm }* esign No. (The design No. is subject to change) : Gasket mount type (G), screw connection type (T) : Flange mount type (F) <With nominal diameter of (¾), 1 (1¼)> 1: Flange mount type (F) <With nominal diameter of 1 ()> Option code No designation: Single pilot type(internal or external pilot type) W: ouble pilot type(internal and external pilot type) Note: * 1 The products are supplied with a function code of as standard. If a product with a function code of 1, 3 or is required, change the setting by referring to the setting guide on Page -. fter changing the setting, correct the model code marked on the nameplate. * Pressure adjustment range code is only applicable to nominal diameter code 1 (). ontact aikin separately for the delivery term of the products that accept phosphate ester hydraulic fluids.

3 efore using the product, please check the Handling The adjustment ranges are indicated using cracking s. For products with a function code of 1 or (internal drain type), connect the secondary side port directly to the tank. For products with a function code of or 3 (external drain type), connect the secondary side port directly to the tank. For products with the adjustment range code, do not change the drain/pilot setting to function code 1 (internal pilot type, internal drain type). Otherwise, chattering may occur. When connecting two or more of these valves for sequential operation, set the valve s such that there is a minimum difference of 1 MPa {1 kgf/cm } between two valves.
