Valve SG, SP-type spool type valve pipe connection or direct panel mounting pressure Pmax = 400 bar flow Qmax = 100 lpm 1, Overview spool type valve is typically used in the hydraulic system of hydraulic oil as medium. Valve for controlling the flow direction, so as to control the actuator (hydraulic cylinder or hydraulic motor) direction. This valve is designed to install a monomer, wherein the leakage balance, therefore, no need to drain port. Various types of valves apply correspondingly;. Pipe connection or direct. Valve plate installed by the control element (spool valve comprises a valve body) and direct manipulation device has been installed in the composition. Full valve member made of steel, which makes the valve body can withstand the pressure shock, nor leakage. Pressure shocks caused by the body after prolonged use of casting can sometimes be observed, manifested in the appearance of fine cracks formed and change, especially when running at full allowable under pressure. In this series of valves, this phenomenon can be completely avoided from the beginning of one. The valve body bore honing magic. Hardened and ground polished off the spool / deburring. These measures ensure that the geometry of its roundness and accuracy (control side will not wear or wider), to ensure proper sealing gap leakage is minimized. Cast material (zinc and aluminum die castings) is used only for non-pressure parts, such as the steering mechanism housing, a spring cover and base. Ductile iron is also available to do manually operated mechanism casing, particularly when used in the harsh conditions and a valve connected in series. SWPN type slide valve solenoid valve nominal size 6 or 10, in line with DIN 24 340 maximum pressure = 350 bar Maximum flow rate = 150 lpm 1, overview, such as direct drive valve spool type valve connected installation face type consistent with DIN 24 340-A6 or A10. Use BA type 2 (according to D 7788) interconnect, can SWPN type 2 valve manifolds connected into use. This can be installed directly on HC (D 7900), HCG (D7900 G), MP (D 7200 H) and HK (D 7600FF) type pump station, or with model BWN (H) 1 + 2, BVZP I and VB 01, the joint use of off-type valve groups 11 and 21. 2, port size and main technical data Order example: SWPN2-G-G24 NSWP2 type spool type valve plate connection structure, in line with the mounting surface DIN24,340-A6 (NG6) standard flow Qmax = 25 l / min pressure Pmax = 315 bar 1, in addition to an overview of the existing SW, SWP2 SWS2 valves and valves, but also developed a new type of valve NSWP2 Features;. Using the standard mounting surface. On the port side of the actuator pressure switch can be set to direct. Can choose different solenoid operated. Has a fast moving and slow switching function. Proportional throttle slide valve structure and the valve has a different rated flow. Pump side, the actuator side to side and back to the oil with additional function 2, the main technical specifications and ordering data sample; NSWP2D06 / MP / R / ABR1,0 / 20 / S-G24 NSWP2G / MM66 / R / 50 / B1, 0-G24 PSL PSM PSV proportional load-sensing type multi-valve size 2 (combined) operating pressure Pmax = 420 bar flow Qmax = 54 L / min size 3 (combined) operating pressure Pmax = 420 bar flow Qmax = 120 L / min size 5 (combined) operating pressure Pmax = 420 bar maximum flow Qmax = 160 (210) L / min 1, an overview of the direction of PSL and PSV proportional multi-way valve is used to control the direction of movement of the hydraulic actuator movement and velocity (stepless manner, and does not depend on the load), to this end, a plurality of actuators can simultaneously and independently of each other at different velocities and pressures of work, until the sum of all partial flow of the pump flow reaches far. The proportion of multi-valve in the sample introduced a modular valve, and consists of three functional components. Connection block with pressure oil pump side and back to the tank interface import P R, in addition to the control interface and measurement interface LS, Z, M selection.

In general, many of the hydraulic actuators and a long pipeline will have an accumulator effect, so as a result of compression of oil in the valve switch will generate pressure shock oscillations at high pressures do not work when the line is clear that in order to eliminate this steady switch oscillation, one possibility is to adjust the valve opening speed, the user can select an own operating conditions (optional) is a throttle valve (commutation time adjuster) according to, so that you can adjust the oscillation time, when the When the control pressure is low, the commutation time regulator effect is very obvious, and very accurate, and the other one, allowing a choice to install a pressure valve on the block in order to limit the makeup even control the pressure, see Chapter 2 for more information. 2. Available varieties and main technical parameters Order example; HSR3 / B31C-G1DGW-2-G24-250 SMD 2 and NSMD type 2 clamping module clamping device for manipulating motorized traffic Qmax = 25 lpm operating pressure Pmax = 120 ... bar set function control, adjustable clamping pressure and clamping pressure of electrical monitoring functions in one device clamping pressure regulation and monitoring by a device; manual or electric proportional control the clamping pressure can be safely monitored. Even if the clamping pressure is very low. pressure control obtained directly in the load port. a dedicated protection circuit monitors the direction of the switching position of the valve. pressure reducing function or for two load ports (A and B) or with only one load oil port (A) .NSMD2 type mounting surface according to DIN 24340-A6 1, an overview, the control unit is designed to install the valve plate, for controlling power-operated clamping device, in particular on the machine automatically tighten chuck (hollow or solid). In common valve body, a solenoid-driven three 4-way or 4-way valve 2, and a 3-way valve with integrated pressure switch. 3-way valve to reduce the inlet pressure to the adjusted clamping pressure port A or B (the secondary pressure side) of the special shape of the valve spool, in the corresponding switching position, communication between the leads under reduced pressure oil control valve, integrated in the micro-valve pressure switch (monitoring the clamping pressure), when there is a certain difference between the set pressure, to trigger a signal, when the regulator control pressure change, the pressure switch can automatically follow, maintain the original target of pressure, and then the pressure switch will make special adjustments. Clamping module is configured to, over the entire clamping pressure setting range, the pressure switch can always give a clear answer or supervisory signal, which clamp pressure by converting pressure associated with relay means to achieve this where, additionally also monitors CAPTURE force adjustment range is lower than the clamping pressure and flow rate, which ensures that, when the tension reaches the cartridge reaches the end position and the clamping pressure, the pressure switch will trigger signal (clamping pressure response). Thus, clip tight clamping module can monitor the entire process (start and end), or pressure due to a fault (e.g., pipe fracture, the pump is not normal) caused the disappearance, the trigger signal for the private wins, clamping pressure and flow curves see Section 4,1 section. Several slide valve function of this valve is applicable, be selected for load modulation of the pressure ports A and B or only selected for ports A, only the spool of a short position before the final instant control and internal communication path between corresponding load port was quickly formed and maintained to the commutation and the return is on. As a result, in fact, only switching valve has reached the selected position, the clamping pressure response signal and pressure monitoring signal only occur. Selection specification;.
