Двунаправленные шиберно-ножевые задвижки с нулевой протечкой, соответствующие ASME Класс 150, предназначены для эксплуатации со шламом и нефтяными песками под высоким давлением
- Full round port and seat design offers low pressure drop across valve and longer service life in abrasive applications.
- True bi-directional flow and Zero leakage* shut-off, can be installed in either direction.
- Compliance to the face-to-face dimensions of MSS-SP135 (short).
- Suitable for dead end service up to full rated pressure.
- Designed as a repairable asset for a lower cost of ownership.
- 17-4 ph stainless steel hardened gate provides improved abrasion resistance against the rigors of abrasive applications.
- Heavy cross section precision molded elastomer seat, held in place by the bolted body to prevent pullout or shifting in the body. Simple to replace, no shimming or trimming.
- Seat is available in EPDM, NBR, HNBR, Natural Rubber, FKM or other elastomers with a maximum temperature rating up to 200°C (400°F) with proper elastomer selection.
- Superior all-around the gate packing assembly, no special tools or unique packing materials to maintain or replace. Optional live-loaded packing for high cycle applications provides continual load.
- Optional fluoropolymer or proprietary SSEC coating can be applied to gate or body. Formulated to minimize media adherence (anti-stick) and improve abrasion resistance; apply to gate to extend seat and packing life or use on the body, interior or exterior, for additional protection.
