SXCA
Direct-acting sequence valve without reverse flow check
SERIES 1 / CAPACITY: 60 L/min. / CAVITY: T-11A
Direct-acting sequence valves will supply a secondary circuit with flow once the pressure at the inlet (port 1) has
exceeded the valve setting. The pressure setting of a sequence valve controls the pressure at port 1 relative to the
pressure at the drain (port 3).
TECHNICAL DATA
Factory Pressure Settings Established at 30 cc/min.
Maximum Operating Pressure 350 bar
Response Time - Typical 2 ms
Maximum Valve Leakage at Reseat 0,7 cc/min.
Adjustment - Number of Clockwise Turns to Increase Setting 4
Locknut Hex Size 15 mm
Locknut Torque 9 - 10 Nm
Seal kit - Cartridge Buna: 990-011-007
Seal kit - Cartridge Polyurethane: 990-011-002
Seal kit - Cartridge Viton: 990-011-006

TECHNICAL FEATURES
All 3 port sequence cartridges are physically and functionally interchangeable (i.e. same flow path, same cavity for a given frame size).
Although this is a zero pilot flow valve, port 3 (drain) must be connected to maintain a pressure reference in the control chamber. If port 3 is blocked, reciprocating
seal weepage will cause the valve to malfunction.

Pressure at port 3 is directly additive to the valve setting at a 1:1 ratio and should not exceed 5000 psi (350 bar).
Suitable for use in load holding applications.
Corrosion resistant cartridge valves are intended for use in corrosive environments and are identified by the model code suffix /AP for external stainless steel
components, or /LH for external zinc-nickel plated components. See the CONFIGURATION section for all options. For further details, please see the Materials of
Construction page located under TECH RESOURCES.
Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge
machining variations.
