HSV Series 3/2 Way Hand Slide Valve | Straight Through Pneumatic Source Slide Switch

Brand: SOLH by Richge Technology | 3/2 Way Self-Locking Hand Slide Valve for Pneumatic Circuit Manual On-Off & Pressure Relief

1. Product Overview

     The SOLH HSV series is a standard 3/2 way hand slide pneumatic valve with straight-through sleeve push-pull structure, fully compliant with AirTAC HSV series specifications and universally interchangeable with domestic equivalent models. Adopting non-spring self-locking design, it realizes air supply on by forward pushing and pressure relief exhaust by backward pulling. With built-in exhaust logic, the valve instantly discharges residual pressure from rear pipelines when closing. It is professionally applied as manual main switch for pneumatic branch circuits and air cut-off safety valve for equipment maintenance, featuring stable self-locking and safe pressure relief performance.

  1.1 Core Air Port Logic & Operating Principle

     • Air Port Definition: P (air inlet), A (working outlet), R (built-in exhaust port)

     • Normally Closed State: P-A circuit disconnected, A-R circuit open for continuous exhaust

     • Working Push State: P-A circuit connected for air supply, A-R circuit closed for pressure holding

     • Operating Feature: Axial sleeve push-pull operation with mechanical self-locking structure, no position deviation after releasing hands

2. Model Coding Rules & Thread Specifications

  Coding Logic: HSV [Port Size] - [Thread Structure Code] + [Thread Type Code]

  2.1 Port Size Specification

     • 06: G1/8 (PT1/8)

     • 08: G1/4 (PT1/4)

     • 10: G3/8 (PT3/8)

     • 15: G1/2 (PT1/2)

     • 20: G3/4

     • 25: G1

  2.2 Thread Structure Suffix Code

     • SF: Standard structure, one end external thread + one end internal thread (most common model)

     • SS: Double external thread at both ends

     • FF: Double internal thread at both ends

  2.3 Thread Type Code

     • Default: PT taper thread

     • G: British standard parallel thread

     • T: NPT American standard taper thread

  Model Example: HSV08-SF | G1/4 port, standard one-external-one-internal thread hand slide valve, the most widely used specification in the market

3. Core Technical Parameters

4. Structural Core Advantages

     • Inline Straight-Through Installation: Designed for series connection in pneumatic branch pipelines, no base required, can be directly threaded and installed in the middle of air pipes for simple and space-saving layout.

     • Safe 3/2 Way Pressure Relief Logic: Pull to cut off air intake and release all residual pressure from rear cylinders and pipelines; push to restore air supply and pressure holding. Effectively eliminates residual pressure hazards during equipment maintenance.

     • Reliable Self-Locking Performance: Mechanical positioning self-locking structure, no spring reset, stable positioning after operation, no accidental displacement or air leakage.

     • Diversified Thread Matching: Multiple thread structures and types optional, perfectly compatible with quick fittings, internal thread joints and KQ2 air pipes for flexible on-site assembly.

     • Durable Anti-Corrosion Structure: Hard anodized aluminum body and stainless steel spool achieve wear resistance, oxidation resistance and long-term stable operation in complex environments.

5. Selection Distinction: HSV Hand Slide Valve vs 4HV Hand Rotary Valve

6. Typical Application Scenarios

     • Single Cylinder Branch Control: Installed between air source and solenoid valve to realize manual air cut-off and residual pressure relief for equipment shutdown and maintenance.

     • Equipment Main Air Cut-Off: Mounted on the main air intake pipeline of tooling equipment for overall rapid pressure relief and safe shutdown operation.

     • Vacuum Circuit Switching: Applied to vacuum pump branch circuits for manual start-stop control; pull the valve to release vacuum pressure quickly and ensure safe operation.

One Sentence Summary

     The SOLH HSV series is a 3/2 way self-locking straight-through hand slide valve with built-in pressure relief function. Featuring lube-free operation, diversified thread options and safe residual pressure exhaust logic, it is the standard manual air source switch valve for pneumatic circuit maintenance and branch on-off control.
