No. Consistency, fibre content, mineral fillers, and differential pressure are all critical factors. An isolation valve cannot simply be substituted for a valve engineered for control.
PULP & PAPER
A pulp and paper mill circulates far more than just pulp. VAMECA provides expert guidance in selecting valves, gaskets, and mechanical packing for fibrous lines, process water, and thermal utilities—delivering trusted, local reliability across Quebec and Canada.

AT YOUR FACILITY
From stock prep lines to dryer cylinders
OPERATING CONDITIONS
SERVICES
Fibres and Deposits
Slurry consistency, suspended solids, and media buildup risks dictate port design, valve sealing requirements, and flushing needs.
MATERIALS
Thermal and Cycling Conditions
For steam and condensate systems, look beyond the design temperature to also evaluate differential pressure, startup sequences, and return conditions.
OPERATIONS
Planned Shutdowns
Prior to replacement, verify overall dimensions, end connections, actuation, and wear parts ahead of your scheduled maintenance window.
APPLICATIONS
Stock Preparation and Transfer
Line isolation, tank-to-tank transfer, and equipment feed. Please specify fiber concentration and whether on/off or modulating control service is required.
White Water and Process Water
Rinse, recycle, and cooling water services. The suspended solids load differentiates these processes from standard clean water systems.
Drying and Heat Recovery
Steam regulation, equipment drainage, and condensate return. Assess load variations and back pressure.
Process Products
Additives and chemicals: document their chemical composition, concentration, and actual operating temperature prior to material selection.
PROCESS SIGHT GLASS
Two pathways to evaluate in tandem to ensure a seamless, fully integrated replacement strategy.

FREQUENTLY ASKED QUESTIONS
A sample or drawing helps determine the exact geometry. Process fluid, pressure, temperature, and flange specifications are also required to confirm the proper material and thickness.
The issue may stem from your piping system: backpressure, inadequate condensate drainage, or load fluctuations. Steam trap selection must be evaluated in tandem with its installation.
