Abrasion resistance - rubber or polyurethane liners to resist slurry particle erosion
Full-bore design for knife gate and pinch valves - prevents solids bridging and line blockage
Chemical resistance to cyanide solutions (CIP/CIL), sulphuric acid (SX-EW), and lime slurry
Bi-directional sealing for knife gate valves where reverse flow pressure is possible
Flushable seal design - provision for water seal flushing to prevent slurry drying in seat area
Replaceable wear components - sleeves, liners, seats must be field-replaceable to minimise downtime
Actuator reliability - heavy-duty pneumatic or electric actuators for remote operation in remote mine sites

What certifications are required for mining & mineral processing valves in Bintulu?
For mining & mineral processing in Bintulu, the applicable standards are: ISO 9001:2015, ASME B16.34, MSS SP-81 (Stainless steel gate valves), ISO 10434 (Gate valves for petroleum), AS 4041 (Australian pressure piping).

Express dispatch available for urgent site requirements. Contact us at +91-9979774557 or sales@vajravyuh.com with your specification and required delivery date.
What type of valve is best for slurry service in a mine?
For slurry service, the two most common choices are knife gate valves and pinch valves. Knife gate valves use a metal blade that cuts through the slurry to close; they are suitable for isolation (not throttling) and work well for slurries with fine to medium solids. Pinch valves use a flexible rubber sleeve that pinches closed - there are no internal metal parts to erode, making them ideal for highly abrasive coarse slurries. The choice depends on solids size, abrasivity, pressure, and whether on/off or throttling control is needed.
What materials are resistant to acid mine drainage?
Acid mine drainage (AMD) can reach pH 1–2 with high concentrations of dissolved iron, copper, zinc, and sulphate. Carbon steel and cast iron corrode rapidly. Suitable materials include: HDPE (polyethylene) for low-pressure lines and valve linings; PVDF (polyvinylidene fluoride) for higher pressure and broad chemical resistance; natural rubber or Linatex lining for moderate acid concentrations; FRP (fibreglass-reinforced plastic) for large-diameter low-pressure applications. For valve bodies, ductile iron with HDPE or PVDF lining is a cost-effective solution for most AMD circuits.
