Deltrol CMM公對(duì)公止回閥

產(chǎn)品描述

---

---

止回閥在微小的壓差下工作。介質(zhì)沿箭頭方向自由流動(dòng)，沿相反方向流動(dòng)將被抑制。

•無(wú)彈性體(無(wú)O形圈)各種介質(zhì)的密封球閥標(biāo)準(zhǔn)

•氣密型球閥可選O型環(huán)/四環(huán)

•整體長(zhǎng)度緊湊

大工作壓力：

黃銅：2,000 psi(138 bar)

碳鋼：3000 psi(207 bar)

不銹鋼：3,000 psi(207 bar)

破裂壓力：

1至2.5psi(0.07至0.17 bar)

需要其他破裂壓力產(chǎn)品請(qǐng)咨詢工廠。

軟座止回閥如果放置一段時(shí)間，會(huì)使橡膠粘附在與其接觸的金屬上。由于粘連，會(huì)導(dǎo)致初始高裂紋點(diǎn)。而程度取決于很多情況(就座時(shí)間，壓力等)。

工作溫度范圍：

-30°F至+ 200°F(-34°C至+ 93°C)

螺紋：

NPTF

材料：

主體：黃銅，鋼，不銹鋼303

球體：不銹鋼440

彈簧：不銹鋼302

滾珠：聚甲奎樹脂

墊圈：不銹鋼304

O形圈/四環(huán)：丁腈橡膠

CMM Check Valve Male-to-Male

Description

Check valves operate on slight differential pressure. Free flow is permitted in the direction of the arrow, positive check in the opposite direction.

• elastomer-free (no O-ring) Leak-Tight Ball Check standard for various medias

• Bubble-Tight Ball Check with O-ring/Quad ring optional

• Compact over-all length

Specifications

Maximum Operating Pressure

Brass: 2,000 psi (138 bar)

Carbon Steel: 3,000 psi (207 bar)

Stainless Steel: 3,000 psi (207 bar)

Cracking Pressure

1 to 2.5 psi (.07 to .17 bar)

Other cracking pressures available.

Consult factory.

Soft seat check valves if left seated for a period of time, will have the rubber adhere to the metal it is in contact with. This results in an initial high crack point due to sticking. The degree depends on many things (time seated, pressure, etc.).

Operating Temperature range

-30° to +200° F (-34° to +93° C)

Threads

NPTF
