As a core type of flow control valve, the throttle valve adjusts the flow velocity and flow rate of fluid in the system accurately by changing the throttle opening through spool displacement, which effectively controls the operating speed of hydraulic cylinders and pneumatic actuators and avoids equipment stuttering and speed fluctuation during start-up and shutdown. The product adopts precision forged valve body and wear-resistant spool with good tightness, no leakage, excellent corrosion resistance and aging resistance, ensuring long-term stable operation. It supports multiple working modes of one-way and two-way throttling with smooth and impact-free adjustment, and realizes stepless speed regulation according to working conditions. With a compact and simple overall structure, it is easy to install and maintain, and adapts to various high and low pressure working conditions. It is widely used in machine tool equipment, engineering machinery, automatic production lines, hydraulic pump stations, water supply and drainage projects and other fields, serving as an indispensable basic control component in industrial fluid control systems.

Throttle plug/Throttle Restrictor

Control Branch Flow Precisely

Equipped with built-in throttle plug inside the 45° branch, it limits flow rate of branch hydraulic circuit by fixed tiny orifice, controls cylinder extension & retraction speed, avoids mechanical shock and jitter, and realizes uniform cushion movement.

Hydraulic Cushioning & Vibration Noise Reduction

Pressure differential generated by throttle orifice absorbs hydraulic impact, cuts down instantaneous peak pressure of pipeline, reduces pipeline vibration and hydraulic whistling noise, protects seals, valve blocks, cylinders and other precision components.

Pressure Division & Stabilization to Protect Downstream Parts

It reduces pressure and limits flow for branch circuits to stabilize working pressure, preventing small actuators from damage caused by direct high-pressure supply.

Integrated Split Flow & Pipeline Routing

Horizontal straight passage serves as main large-flow oil path, and the 45° angled port leads separate controlled branch. It replaces the combination of separate throttle valve and elbow to greatly save installation space of hydraulic manifold. The 45° design has lower flow resistance than 90° elbows, suitable for compact mounting spaces.

Quick Throttle Specification Replacement for Easy Commissioning

The top hex lock nut is detachable. Users can replace throttle plugs with different orifice sizes directly without disassembling the whole pipeline to adjust flow limiting capacity, matching speed regulation demands of different equipment.
