SUN阀PVJBLAN技术参数

SUN阀PVJBLAN产品介绍

可通风的先导式减压/泄压阀可将入口处的高一次压力降低至端口 1 处的恒定减压，并具有从端口 1 到油箱（端口 3）的全流量泄压功能。排气口（端口 4）可用作通过先导阀或二通阀进行远程控制的方法。

• 端口 3 处的压力以 1:1 的比例直接添加到阀门设置中，并且不应超过 3000 psi (210 bar)。

• 先导阀在减压和泄压模式之间表现出非常低的死区过渡。

• 推荐的最大入口压力由调节范围决定。 D、E、N 和 Q 系列在入口压力和减压压力之间的最大压差为 2000 psi (140 bar) 的条件下进行测试。 A、B 和 H 系列是在入口压力和减压压力之间的最大压差为 3000 psi (210 bar) 的情况下进行测试的。 C 和 W 系列是在 5000 psi (350 bar) 入口压力下进行测试的。

• 先导阀表现出异常平坦的压力/流量特性，非常稳定且滞后性低。

• 从减压（端口 1）到入口（端口 2）的完全反向流动可能导致主阀芯关闭。如果回路中需要反向自由流动，请考虑在回路中添加单独的止回阀。

• 通过控制排气口（端口 4）处的压力，可以将阀门的有效设置控制在标称阀门设置以下。

• 采用 Sun 浮动式结构，更大限度地减少由于安装扭矩过大和/或型腔/墨盒加工变化而导致内部零件粘合的可能性。

Ventable, pilot-operated pressure reducing/relieving valves reduce a high primary pressure at the inlet to a constant reduced pressure at port 1, with a full-flow relief function from port 1 to tank (port 3). The vent port (port 4) can be used as a means for remote control by pilot or 2-way valves.

• Pressure at port 3 is directly additive to the valve setting at a 1:1 ratio ａnd should not exceed 3000 psi (210 bar).

• Pilot operated valves exhibit very low dead-band transition between reducing ａnd relieving modes.

• Recommended maximum inlet pressure is determined by the adjustment range. Ranges D, E, N, ａnd Q are tested with a 2000 psi (140 bar) maximum differential between inlet ａnd reduced pressure. Ranges A, B, ａnd H are tested with a 3000 psi (210 bar) maximum differential between inlet ａnd reduced pressure. Ranges C ａnd W are tested with 5000 psi (350 bar) of inlet pressure.

• Pilot operated valves exhibit exceptionally flat pressure/flow characteristics, are very stable ａnd have low hysteresis.

• Full reverse flow from reduced pressure (port 1) to inlet (port 2) may cause the main spool to close. If reverse free flow is required in the circuit, consider adding a separate check valve to the circuit.

• By controlling the pressure at the vent (port 4), the effective setting of the valve can be controlled below the nominal valve setting.

• 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.
