Counter-Balance & Motion Valves

VOSL/SC Series Aluminium body - Steel bodied units available on request - add suffix AC This valve controls a moving load preventing it from moving ahead of the pump and locks the load in any position on U1. It also provides static overload and thermal expansion protection when used in combination with an open centre spool valve. This valve permits free flow from D1 to U1 and blocks the flow from U1 to D1 until a pilot pressure generated at D2/U2 is sufficient to pilot the U1 port open.

VOSL/SC/CC Series Aluminium body - Steel bodied units available on request - add suffix AC This valve controls a moving load preventing it from moving ahead of the pump and locks the load in any position on U1. It permits free flow from D1 to U1 and blocks the flow from U1 to D1 until a pilot pressure generated at D2/U2 is sufficient to pilot the U1 port open. It utilised in combination with a closed centre valve. It is recommended to fit a port relief in this application.

VODL/SC Series - Aluminium body - Steel bodied units available on request - add suffix AC This valve controls a moving load in both directions preventing it from moving ahead of the pump and locks the load in any position on U1 and U2. It also provides static overload and thermal expansion protection when used in combination with an open centre spool valve. This valve permits free flow from D1 to U1 & D2 to U2 and blocks the flow from U1 to D1 & U2 to D2 until a pilot pressure generated at D1 or D2 is sufficient to pilot the U1 or U2 port open.

VODL/SC/CC Series - Aluminium body - Steel bodied units available on request - add suffix AC This valve controls a moving load in both directions preventing it from moving ahead of the pump and locks the load in any position on U1 and U2. This valve permits free flow from D1 to U1 & D2 to U2 and blocks the flow from U1 to D1 to D2 until a pilot pressure generated at D1 or D2 is sufficient to pilot the U1 or U2 port open. It is utilised in combination with a closed centre spool valve. It is recommended to fit a port relief in this application.

Steel Body -The 1116 series is built with zinc plated steel bodies to ensure a high level of strength and durability. These valves can reach a working pressure of 400 bar. N1116 Series - This valve controls a moving load preventing it from moving ahead of the pump and locks the load in any position on U1. It also provides static overload and thermal expansion protection when used in combination with an open centre spool valve. It permits free flow from D1 to U1 and blocks the flow from U1 to D1 until a pilot pressure generated at D2/U2 is sufficient to pilot the U1 port open. This model is sensitive to back pressure on D1 in return mode. R1116 Series - As per N1116 but is sensitive to back pressure on D1 in return mode. V1116 Series - As per N1116 but has the spring chamber isolated from any system back pressure by a seal and is vented to the atmosphere. It is ideal for use with closed centre spools.

Steel Body - The 1116 Series is built with zinc plated steel bodies to ensure a top level of strength and durability, these valves can reach a work pressure of 400 bar. N1116 Series - This valve controls a moving load preventing if from moving ahead of the pump and locks the load in any position on U1 and U2. It also provides static overload and thermal expansion protection when used in combination with an open centre spool valve. It permits free flow from D1 to U1 and D2 to U2 and blocks the flow from U1 to D1 and U2 to D2 until a pilot pressure generated at D1 or D2 is sufficient to pilot the U1 or U2 port open. This model is sensitive to back pressure on D1 and D2 in return mode. R1116 Series - As per N1116 but is insensitive to back pressure on D1 or D2 in return mode.

Steel Body - The 1516 Series is built with zinc plated steel bodies to ensure a top level of strength and durability, these valves can reach a work pressure of 400 bar. All valves in the range are equipped with pilot signal restrictors to ensure smooth and safe operation in every load handling application. N1516 Series - This valve controls a moving load preventing it from moving ahead of the pump and locks the load in any position on U1. It also provides static overload and thermal expansion protection when used in combination with an open centre spool valve. It permits free flow from D2 to U2 and blocks the flow from U2 to D2 until a pilot pressure generated at D1/U1 is sufficient to pilot the U2 port open.
