GENERAL

The H-700 Series is a moderate-pressure ball valve for general service. These valves are compact in size and structure. They have relatively large ports for high flow, tight shutoff, long-life service and low operating torque.
The H-700 Series can be used for bi-directional flow in fully open or fully closed position only. The series is rated to max. 2000 psig (135 bar) and performs
on/off service.

SEAT MATERIAL CHARACTERISTICS
TFM®1600 – (PFA and PTFE composite) – Bright White.
Excellent seat material for purity applications, very low residual material during operation. It has lower deformation ratio than PTFE, but higher pressure and temperature rating. Chemical resistance is equal to PTFE material.

PACKING ADJUSTMENT
Due to the varied service applications of the valve, packing adjustment may be occasionally necessary. Packing is factory adjusted to 1000 psig service. Initial packing adjustment is recommended after installation and prior to start-up. Please find more information on H-700 under installation instruction. HAM-LET Ball Valves are designed to be operated in the fully closed or fully open position.
