Product catalog summary

Throttle (Needle) Valve Series Overview
The document provides comprehensive details on the Throttle (Needle) Valve Series, including types such as Stainless, PP, and Anti-spatter Series. These valves are designed for controlling actuator speed or pneumatic signals with adjustable flow rates and optional body colors.

Specifications

Fluid Medium: Air
Operating Pressure Range: 0 to 0.9 MPa
Max Vacuum: -100 kPa
Operating Temperature Range: 0 to 60°C (No freezing)

Construction Details

Elastic Sleeve (NBR)
Taper Pipe Thread: Sealock Coating
Metric Thread: With Gasket (SPCC+NBR)
Resin Body: PBT
Metallic Body: Nickel-plated Brass

Safety Instructions

Adjust the needle slowly from a fully closed state to control actuator speed.
Avoid forcefully swinging or rotating the resin body to prevent damage and leakage.

Installation and Adjustment

Use a spanner to tighten hexagonal columns according to recommended torque.
Speed adjustment is achieved by turning the needle counterclockwise to increase speed and clockwise to decrease it.

Flow Characteristics
Flow characteristic charts illustrate the relationship between needle rotations and flow rate under various pressures.

Model Designation and Options

Model codes specify type, tube diameter, thread size, color, and packaging options.
Color options include standard black and light-gray for clean-room packages.

Additional Information

CAD data is available on the PISCO website for detailed design and integration.
Special specifications and characteristic charts are referenced for further customization.
