Pliant PTFE bodies of the valves are reinforced by structurally rigid metallic shells. Fluids contact only PTFE and CTFE materials. Shells are made of anodized aluminum or type 316 stainless steel and bushings are made of plated
brass or 316 stainless steel. Where externally corrosive conditions exist stainless steel is recommended. Valve spindles are made of rigid CTFE to minimize the undesirable material “creeping” normally associated with PTFE.
Valves may be used in pressure or non-critical vacuum service. The simplicity of design - there are only seven components (including a single PTFE o-ring) - assures reliability and minimizes sources of leakage. It takes seconds to disassemble the valve for cleaning and maintenance. The PTFE o-ring is radially compressed and due to this unique design feature the degree of compression
may be adjusted without disassembly by tightening the hexagonal bushing.
PTFE valves are designed for relatively high flow ranges while still performing well
in low flow rates.
