• Internal passages finished to 0.1 to 0.4 micro-meters (4 to 16 micro-inches) RMS to ensure easy flow of fluid.
• Flow passage designed to prevent flow stagnation and polymer degradation.
• Bellows seal is available.
• All HVP Series control valves can be vacuum rated.
• Integral valve body jacketing for efficient heat transfer and stabilized flow.
