PNEU-HYDRO直角泄压阀系列介绍及选型

Pneu-Hydro 直角泄压阀采用内部压力平衡设计，压力参考大气压。这使得该阀对下游压力不敏感，并可用作背压调节器。

该阀采用弹性阀座密封，并利用金属限位挡块承载弹簧载荷，从而延长密封寿命并确保可靠的泄压性能。该设计可在极小的开启压力上升幅度下实现全流量。

特点与优势

• 提供多种泄压设定范围

• 可根据客户要求提供精确的工厂设定泄压压力

• 外部可调

• 可用作背压调节器

• 性能平稳、无抖动

• 可靠且可重复的开启压力和复位压力

• 316 不锈钢结构

Pneu-Hydro Right Angle Relief Valves are pressure balanced internally and pressure referenced to atmosphere. This yields insensitivity to downstream pressure and permits the valve to also be used as a back pressure regulator.

The valve seals against an elastomeric seat and utilizes a metallic positive stop to carry the spring load, prolonging seal life and ensuring reliable pressure relieving performance. The design provides full flow at a very small rise above cracking pressure.

Features & Benefits

• Wide series of available relief pressure set ranges

• Precise factory set relief pressure per customer specification

• Externally adjustable

• Can be used as a back pressure regulator

• Smooth, chatter-free performance

• Reliable and repeatable cracking and reseating pressures

• 316 stainless steel construction

PNEU-HYDRO接口阀系列介绍及选型

Pneu-Hydro接口阀采用活塞式气动执行器控制三通两位液压阀。该阀有常开和常闭两种型号，可承受高达 10,000 psi 的液压压力和高达 1,000 psi 的先导压力。

独特的滑阀设计允许使用活塞式执行器，从而消除了先导膜片常见的故障和泄漏，同时确保了在恒定的低先导压力下安全可靠的运行；5,000 psi 液压压力时，先导压力为 50 psi；10,000 psi 液压压力时，先导压力为 80 psi。

弹性密封和金属密封的组合确保了液压动力部分可靠的零泄漏性能。由于内部弹簧和作用于差动阀芯区域的液压均能提供足够的力，从而确保故障安全关闭，即使其中一个发生故障也能实现关闭。

阀芯延长部分配有操作指示器，可移动以显示位置，手动超控版本在活塞壳体顶部中心处配有旋转手柄。

Cv = 0.5 的值或相当于 0.224 英寸直径孔口的值可提供的流动能力。

Pneu-Hydro Interface Valves utilize a piston style pneumatic actuator to control a three-way two position hydraulic valve. Configured in both normally open and normally closed versions, these valves can accommodate hydraulic pressures up to 10,000 psi and pilot pressures up to 1,000 psi.

The unique spool valve design permits the use of a piston style actuator, eliminating the common failures and leakage associated with pilot diaphragms, while also ensuring safe and reliable operation with consistent low pilot pressure; 50 psi pilot at 5,000 psi hydraulic, and 80 psi pilot at 10,000 psi hydraulic.

A combination of elastomeric and metal seals ensures reliable zero leakage performance in the hydraulic power section. Failsafe closure is ensured, as both the internal spring and hydraulic pressure acting on the differential spool area provide sufficient force to effect closure should one or the other fail.

A positive indicator of operation is provided in the spool extension, which shifts to show position, and the manual override version has a turning handle located at the top center of the piston housing.

Excellent flow capacity is provided with a value of Cv = 0.5 or the equivalent of an orifice of 0.224 inch diameter.
