Product Features

Designed to meet various requirements for abrasion, corrosion, temperature, and pressure;
Functions both as a pump body and for slurry handling, performing effectively even with ungranulated and high-density materials;
Provides 100% isolation with bubble-tight sealing for absolute zero leakage;
Heavy-duty, field-replaceable elastomer sleeves with internal reinforcement rings;
Double-gate design enables bi-directional flow sealing;
Unobstructed or dynamically stabilized airflow minimizes valve pressure drop;
Prevents any solid particle accumulation on the gate that could hinder valve closure;
No metal parts are exposed to slurry contact;
No need to adjust or lubricate packing, eliminating leakage and maintenance issues;
Flexible frame (bracket) design allows for installation onto existing gate stem nuts.
Applications: Mining, Mineral Processing, Power Generation, Chemical Industry, Pulp and Paper Industry, Cement Industry
