Electric V-Type Pinch Ball Valve with Hard Seal Wear-Resistant Cut-off Adjustment for Mud Particle Coal Ash

TIANYU Electric V-Type Hard Seal Ball Valve: Wear-Resistant Solution for Particle Media Control

I. Technical Overview

II. Core Product Features

(A) V-Shape Hard Seal Shearing Structure

• Wear-Resistant Shearing Design: V-shape cut core with Stellite overlay (HRC60~65) on 304 stainless steel forms a metal hard seal with 2Cr13 nitrided seat, shearing fibers up to 2mm diameter, ideal for slurry and coal ash water;
• Precision Flow Regulation: Equal percentage flow characteristic with 50:1 regulation ratio, enabling linear control within 0~90° rotation, 25% higher accuracy than standard ball valves;
• Low Flow Resistance: Smooth flow path when fully open, resistance coefficient ≤0.9, 35% less pressure loss than globe valves, saving ~8,000kWh annual pumping energy.

(B) High-Strength Material System

(C) Intelligent Electric Drive System

• Rapid Response: 220VAC motor drive, DN100 opening/closing time ≤15s, supports 4-20mA signal for DCS integration;
• Safety Redundancy: Built-in limit switches and overload protection, manual operation (≤120N·m torque) during power failure;
• Enhanced Protection: Anodized aluminum actuator housing, IP65 protection against water and dust.

IV. Manufacturing Processes & QC

(A) Precision Manufacturing

1. Body Forming:
   • WCB cast steel via resin sand casting, UT-tested for defects, annealed to relieve stress;
   • 316 stainless steel body via centrifugal casting, surface roughness Ra≤12.5μm.
2. Core Machining:
   • 5-axis CNC machining for V-shape cuts, angle error ≤±0.3°, fit gap with seat ≤0.03mm;
   • Stellite overlay aged at high temperature to enhance bonding strength.
3. Assembly & Testing:
   • 1.5x pressure (2.4MPa) hydrostatic test for 30 minutes without leakage;
   • Sampled for 100,000 cycles with ≥95% sealing retention (industry standard: 50,000 cycles).

(B) Quality Certification

• Material Traceability: Batch number management for key components, traceable to heat number and chemical reports;
• Third-Party Inspection: Supports SGS, BV certification for material, pressure, and sealing;
• System Certification: ISO 9001, CE certified, some models comply with API 598.
