Parker N35461091 Pilot Air Control Valve High Precision High Safety New

Product Specification

Product Description:

1. Advantages and Features

High precision and fast response

Using proportional solenoid and high-precision position feedback system (such as D41FH series), the steady-state error can be controlled within ±0.5%, supporting precise flow regulation and dynamic position monitoring;
Millisecond response time, suitable for high-frequency action scenarios (such as automated production lines), and low hysteresis design to improve process repeatability.

Modular and compatible design

Compliant with ISO 5599-2 standard interface, supports quick plug-in installation (such as KA series directional valve), simplifies system integration and maintenance;
Multiple drive modes are optional (electromagnetic, hydraulic, pneumatic), suitable for complex working conditions, such as dual valve core actuators to control multi-action equipment.

Durability and safety protection

Hardened stainless steel plunger and hardened alloy valve core, wear-resistant and corrosion-resistant, significantly extended service life (such as D41F series);
P33 safety exhaust valve supports EN ISO 13849-1 standard, dual-channel redundant design and solid-state pressure sensor, zero delay in fault monitoring, and rapid discharge of residual energy during emergency shutdown.

‌Multi-function and energy-saving features‌

Integrated protection functions such as main overflow valve and hydraulic control check valve, support flow priority adjustment and closed center position design to reduce energy loss;
Soft start function can smooth pressure loading, reduce equipment impact and extend system life.

2. ‌Precautions for use‌

‌Installation and commissioning specifications‌

It needs to be installed vertically or horizontally to ensure that the interface direction is consistent with the medium flow direction, and the flange bolts are tightened symmetrically to avoid eccentric load;
Before the first start, it is necessary to fully exhaust and gradually pressurize and debug (the recommended initial pressure is 20%~30% of the rated value) to prevent the seal from being damaged by instantaneous high pressure.

‌Medium and environmental requirements‌

The cleanliness of the hydraulic oil must meet the NAS 1638 level 6 standard. Medium containing particles or high viscosity media can easily cause the valve core to jam, and the filter element needs to be cleaned regularly;
The operating temperature range is -10~80℃. In high temperature environments, a heat dissipation device must be configured or a high temperature resistant coil (such as a fluororubber seal model) must be selected.

‌Operation and load limit‌

It is forbidden to operate over the rated pressure (such as the maximum continuous pressure of D41FH series is 25MPa). Long-term overload may cause valve body deformation or gear breakage;
Avoid frequent start and stop and sudden load changes to prevent impact loads from affecting the positioning accuracy of the valve core.

‌Maintenance and parts replacement‌

Check the status of the seals every 500 hours. When replacing, use original parts (such as propylene rubber seals) to ensure compatibility;
Before long-term shutdown, the residual medium in the system must be emptied and anti-rust oil must be injected to protect internal components (such as plungers and bearings).

‌Key tips‌:

Multi-valve linkage requires PLC calibration of synchronization parameters to avoid system conflicts caused by action delays;
Before disassembly and maintenance, the pressure must be released and the power supply must be disconnected to prevent accidents caused by residual energy.
